Matlab Controls – Utility Grid With Gui

November 17th, 2011 Comments off

It is the end of the college semester and frankly I am not going to become a controls guru programming class that is required for graduation. I have completed all programs in this semester myself but I have far too big of a time demand on other classes that these project are getting hired help.

Note: All programs above are to be in MATLAB format using a GUI (GUIDE). I’ve created a rough draft GUI so far and can email it for reference.

This project will basically consist of taking mulitple …

Matlab Trading Strategies Back -testing Framework

September 22nd, 2011 Comments off

We need someone to write functions/ scripts in Matlab to backtest trading ideas. This will form a general backtesting framework with ability to handle many different way of managing the position etc..

The project should include among others:
1) Build the position in a flexible way
- the positions stays in play until cancelled or is only cancelled after a certain period etc..
- implement stops and profit taking by value and %
- Optimal exit using trailing stop
- MAs crossover for entry and exit
- Optimization of entry and exit based on time (optimal time of entry/exit, e.g. 4 days to contract expiry)

2) Calculate the Pnl and performance
- Maximum drawdown, average drawdown
- sharp ratios
- PnL, Cumulative Pnl
- % Wins (losses)
- Average gain in $ terms given the preset size of 1R in $
- Standard deviation of returns

Customised Matlab Program (som Toolbox)

August 19th, 2011 Comments off

There is a small and simple Matlab program that needs enhancements, and a resulting dataset to be used on a SOM clustering and classification. A GUI aplication is to be made. The details are simple: GUI, the present program enhancement, with the program variable conditions at the GUI (import, standardize, calculation results output, SOM options and outputs, classification of clusters through the specified method, identification of original units with the new classes) a SOM applied, all the quality measure provided (graphical e non graphical) then compute a metric to classify the SOM clusters into a computed codebook from the BMU average of the trained network; this codebook will be used to unsupervised classify the computed SOM clusters. A class quality metric should computed, based on the class density of the trained network. The attached file is to be used as an example.

Matlab Simulation (wireless And Fiber Optic Communication)

April 23rd, 2011 Comments off

There should be a random data generator where digital data is produced, this data is produced with source coding and channel coding and modulated by any modulation scheme (m-psk or m-qam here m is a integer 8 there should be option for it). for mobile communication pilot and zero padding should be added with data before modulation. this processed data should be pass though channel
Task a: wire less channel (AWGM fadding)
Task b: optical channel
this transmitted data should be received and this received data should be demodulated (viterbi technique for wireless communication). After demodulation the received data should have some error. the error should be count in the error count diagram. form this error we have to calculate the Bit error rate (BER) and have to plot the BER vs SNR figure(attachment).
Also we have to show the consolation diagram of th system.

there should be two different file for the wireless and fiber optic communication.
i prefer MATLAB simulink than coding……… the project will look same as my attachment on MS word… all the boxed are provided in MATLAB simulink…… you have to link all the equipments by fixing the parameters so that they can work synchronously and give a valid result.

Homework Assignment – Matlab

April 11th, 2011 Comments off

This is a simple homework assignment in matlab requiring you to build a GUI(you may use GUIDE, the swings equivalent for Matlab) which can encrypt & decrypt files using the DES, RSA & AES algos. Algos must be implemented and may not be inherited from previously defined classes. I have included two samples of DES mentioning how the backed code should work.

Convert And Modify A C++ Code To Matlab Code

April 10th, 2011 Comments off

Hi scriptlancer,
I need a matlab code written for D* Lite algorithm. The algorithm and C++ code are available.

Algorithm: Figure 4 of this paper –> http://idm-lab.org/bib/abstracts/papers/aaai02b.pdf

C++ code: http://freshmeat.net/projects/dstar/

I want the output of the algorithm to display in an interactive plot just like http://by-expert.com/plot.zip

Basically, the algorithm is a path search algorithm like A* search. If you have worked on any kinds of graph search algorithm before, please mention that in your PMB.

The matlab code has to be well documented with comments in every line.

I need the work done by tomorrow Tuesday (12/4/2011)

C++ / Matlab Simple Project. ( Easy)

April 8th, 2011 Comments off

Please see the attached file for details.

Write a MATLAB main .m file and one function m file that executes the following:
a. The main file opens the data file noisedatapa5.txt using fopen and fscanf to read the dc, gt, and snr values into arrays. (You must use the exact file provided with the problem statement including the text headings.) To read lines of text in MATLAB you use the function fgets . (To learn how to use fgets, type help fgets at the command line prompt.)

b. The main m-file uses polyfit, to determine the slopes (a[i]) and intercepts (b[i]) of the best fit lines of snr (y) vs. gt (x) for each value of dc (there are five values of dc). The equation is: snr = a[i]*gt + b[i] for a given dc (You will determine a[i], b[i], for each value of dc, where i ranges from 1 to 5, and is related to the different values of dc.)

c. The main m-file calls a function that you write and sends it the values of gt and snr for each dc value and finds the corresponding rsquared[i] values. The function returns the rsquared[i] values to the main m-file. The main m-file then prints a well-formatted and labeled table to the screen showing the values of slope, intercept and rsquared. (Example below.)

d. The main m-file prompts the user for a design value of snr (call it snrinput), and determines, using the relationships and coefficients determined in part b, an array of gt[i] values that will give the input value of snr for each dc data value. (Or in other words: gt[i]=(snrinput – b[i])/a[i] ; where i ranges from 1 to 5.). The resulting gt[i] values are stored in an array.

e. The main program then uses polyfit again to determine the slope and intercept of the gt[i] values determined in part d vs. the five dc values using this equation:
gt = E1*dc + E2 (Where E1 and E2 are unique for the chosen snrinput).
The main program then writes the values of E1, E2 and the chosen snrinput to the screen in a well-formatted manner.

f. The program then uses the approximate and empirical relationship that cost is proportional to the product of gt and dc to arrive at the optimum cost gt and dc:

derivation follows

cost = k*(dc*gt) (where k is a constant that will cancel out)

substituting in the relationship of gt and dc:
cost = k*(dc*(E1*dc + E2))

Take the derivative of cost with respect to dc, and set it equal to zero:
d(cost)/d(dc) = k*(2*E1 *dc+E2) = 0

solve for
dc = -E2/(2*E1)

substitute this dc of minimum cost into the gt dc relationship using E1 and E2:
gt minimum cost = E1*(dc minimum cost) + E2

These results (dc and gt for minimum cost) are printed to both the screen and the results.txt file in a well-formatted manner.
Reminder: Always display units with numbers when appropriate.

g. The main m-file then plots two figures: one that shows the best fit of the raw data (snr vs. gt) and the derived relationship of gt versus dc for the input value of snr.

Edit Matlab Code

September 4th, 2009 Comments off

I have a pretty basic matlab program that is written inefficiently and I need it to run more quickly. The inefficient sections mostly contain matrix manipulation. The entire program is about 1500 lines.

I am looking for a very careful programmer who is comfortable working with matrix algebra in Matlab. I will send you the program and ask for specific proposals from you to make the program run with less computational intensity. Specifically, I will ask you to rewrite sections of code and explain how replacing the original section with your proposed section will increase the efficiency of the program. The program is very inefficient now, and takes several days to run (although it can be made to run quickly by changing parameters for debugging purposes.)
