I'm actually having trouble with the equalization of the channel, because the doppler effect introduces phase rotation, which I don't know how to correct. If anyone could help me, I' d be really thankful..

After the run of the "MyEqualizer.m" file a graphical user interface appear. By pressing the "Load" we can load audio signal (type .wmv). After we can model the frequency behavior of the FIR filter that is used to filter that signal. After we can listen the filtred audio signal by pressing the "Play " button. In the GUI M-file I'm using three importanat function: [ ]=coeff() that generate cell contain the coefficient of the equalizer, equalizer_plot() who plot the frequency behavior of equalizer and the equalizer_play who filter and play the filtered audio signal..

to run it: you will need first to run the file that name "charGUI4.fig" and on the right side there is a load training set where you have to train the system first, run any data that is should be from 1 to 9 and 0 like ( 1 2 3 4 5 5 6 7 8 9 0) as many line as you want so if you have a traning data that is 10 columns by 5 lines then you have to assign that to the small boxes that name column and line. right now keep the #words as is because I plan to use it but I change my mind so that it is automatically count the word for you. after you train the system then load any image test, from the "Load Image" once you upload the image then choose the "select" and then go to the uploaded image and select whatever you want to recognize, after that select "crop" to crop the exact part that you want to recognize after that selcet "Features...

This is a basic cell tracker for use on uncompressed AVI files, ideal for use with videos where the image of the cell overlap much frame-to-frame. If you use it to generate data for publication please cite the conference paper in the readme file, which you might want to read anyway if you want to use. Sample video to track and paper available at lab website: bme.virginia.edu/lawrence. I'm working on a multiparticle version of the algorithm which also better tracks low-temporal resolution data and compressed input formats. I will post it when I work more of the bugs out. Please contact me if you are interested in the alpha version.

- Sortable Profiler Report
- License: Freeware
- Price: 0.00

The MATLAB 'profreport' function used by the profiler generates a table of function calls sorted by execution time. However, often it is necessary to sort by number of calls, time in self, etc. 'SProfReport' duplicates all the functionality of the original, but permits the function call to be sorted. This is accomplished by use of a simple javascript function. I'm not a javascript expert, and the script I'm using is freeware from the web. Currently sorting will only be in descending order (which is usually what one cares about when profiling). I'd appreciate any improvements to the sorting algorithm.

I installed Microsoft Visual Studio(MVS) 2008 and Matlab R2007b and tried "mex -setup" command from Matlab. However my MVS 2008 was not recognized by Matlab. I debugged mex.m and found a way to show MVS 2008 to Matlab. Necessary files are located at 2 different directories in zip file (VS2008MATLABMexCompilerFilesX64 and VS2008MATLABMexCompilerFilesX86), one is for win32 Operating System(OS) and the other one is for win64 OS. There is also "directory.txt" file in the zip which shows the directory that you should copy necessary files to. I'm using VISTA ultimate edition, but this may work for other OS(not tested).

Allows connection to MBTrading for either simulated trading (delayed quotes and fake money) or real trading (real-time quotes and actual funds). Various files for account connection, quotes and orders. So far not very well documented... work in progress. Also requires the free MBTrading SDK www.mbtrading.com I am not affiliated with MBTrading. I chose their brokerage based on the flexibility of their SDK. Please contact me if you add anything on. I'm constantly expanding the MATLAB code based on the MBTrading connection and would love additions from other developers. Contact me at rissacher@hotmail.

- initializePhysicalConstants.m
- License: Freeware

initializePhysicalConstants.m loads important physical constants into the structure CONSTS. The CONSTS structure will contain both values (accessible by CONSTS.var_name), and descriptive information (CONSTS.desc.var_name.[Name, Units, Value]). EXAMPLE USAGE: % What are the units of the unversal gas constant? CONSTS.desc.R ans = Name: 'Gas Constant' Units: 'J K^-1 mol^-1' Value: 8.3140 % Atoms in 10 grams of oxygen: V = 1; %L P = 1; % atm T = CONSTS.T_o + 20; % K nMols = P*V / (CONSTS.R*T) nMols = 4.1030e-004 % How may atoms? nAtoms = nMols * CONSTS.N_a nAtoms = 2.4708e+020 This program can be vastly improved; I'm happy to do so if people actually use it.

Slow and dirty way to save a simple structure to an Excel file with xlswrite. I did it to solve a urgent problem for a friend. Lots of improvements possible, I'm sure. STRUC2XLS (FILE,S) writes the contents of structure S to a excel file named FILE. The name of the worksheet and the starting row and column can be specified as optional arguments. Example: s=struct('one',[1,2],'two',[10,20,30],'three',[100,200,300,400]); struct2xls('s2xls',s,'Row',4,'Col','D').

- myblob_testdb
- License: Shareware

This function is based on MyBlob toolbox, and it's used to create test environments starting from existing databases, copying a fixed number of elements from eache table of the source database to test one. I'm not related to the author of MyBlob Toolbox: if you don't like this function it's my fault, not his one. myblob_testdb(conn,sourcedb,testdb,limit) - conn is the object to connect to sourcedb obtained by myblob_open; - sourcedb is the name of the source database; - testdb is the name of the destination database; - limit is the number of elements you want to copy from each table; you can set it to 'all' if you want to create an exact copy of the source database.

The function takes in n money line odds. For example a soccer match, +100 for an underdog win, -125 for the favored team to win, and +220 for a draw. The function calculates the percentage of your bet that should go to each outcome in order to minimize your loss no matter what event actually occurs. I'm mainly curious if I coded it correctly, so I would really like some input. I am convinced that for n=2 it works, but I'm not sure about highr n's..

- uithumb

UITHUMB creates thumbnails from images listed in a specified directory. It's not nearly as fast as programs like photoshop, but for those who don't mind or don't have the means, this gets the job done. I wrote it specifically to create thumbnails for my MOSAIC software. As of now, the largest thumbnail it will allow you to produce is 133 x 100, and the output is only jpeg, but this could be modified in the code. The code is not well documented and I don't plan on making any changes to it, but feel free to modify it to your heart's content. As far as help goes with this, I didn't include any, so I'm sorry about that.

Simple user interface with possibility to pick any color and determine MATLAB code for chosen color. It makes possible to copy determined color code en paste it to your color specification within m-file of other program code. This color specification is not RGB value but percentage of RGB. I'm found it useful if you want to assign many colors in your program code and you want to determine a percentage easily..

I've been a fan of OpenID ever since it first turned up on the web, when they were offering bounties for implementing it in popular web apps. So I'm very happy about the scale of adoption it's achieved, and since I've started seeing places where you can use your OpenID to post comments on blogs etc. I thought it was about time I figured out what I needed to do to use my own URL as an OpenID, instead of the generic Launchpad one I've been using most recently. It didn't take long to discover that all I need is a couple of link tags in the document head element of my homepage, pointing to an OpenID authentication server and the "real" URL it can authenticate.
