pcolor not working on my PC only.
Hi, it seems that pcolor is not working on my PC. But only on my PC. I have some code that our professor gave us to simulate some cellular automata - whatever that is. pcolor is supposed to accept an array of 1s and 0s and color a figure based on the array. For every cell with a 1, it makes that pixel black; the oth... 26 Jan 2010 16:38

optimal number of cluster
Hello everyone, These days are so hard for me. :) Climate change changes me every point of me. :) Anyway, now i have a problem, i am already problem for life may be. :) Now, let us think a space or matrix which is dimension is infinite. And, datas have a similarity a bit or too close. Now, in my mind, optimal nu... 23 Jan 2010 13:11

Simulink "time-average" value (Moyenneur)
Hi, I can't figure out how to simply model on Simulink (without using m-function or s-function) the following operation: s(k) = (1/N) * [e(k) + e(k-1) + e(k-2) + .... + e(k-N)] with N>=1 configurable. with e for input, s for output Thanks in advance ... 25 Jan 2010 09:24

I am trying to read in a text file which contains data from an oscilloscope. The file has 5 columns with a header for each channel and time. The columns have been tab delimited. I have not been able to successfully read in the file for some reason. I tried to use textscan and textread with no success. I want to read in... 22 Jan 2010 11:47

creating a GUI for simulink model
I am a beginner of simulink and have created a simple model. Instead of using a GUI at the minute i just have constants all the way down the left hand side of my simulink model. How do i create a GUI where the user can enter these values instead of having to change the constants on the model in simulink? ... 22 Jan 2010 11:47

JMatLink and new version of Matlab
You may need to fix your environment variables. When I installed R200b, it removed the %MATLAB%\bin\win32 entry from my PATH variable. The JMatLink .dll requires this and %MATLAB%\bin be on your path. (%MATLAB% is your Matlab installation directory, typically C:\Program Files\MATLAB\R2009b) ... 5 Feb 2010 08:18

mex file crashes Matlab on 64-bit system
Hello, I just switched to a 64-bit system and now the mex-files which did fine on a 32-bit are now causing a segmentation fault. I DID re-compile the fortran source files on the 64-bit system without any errors but apparently something needs adjustment. Here is one of the short examples: #include <fintrf.h> ... 2 Feb 2010 15:20

nlinfit & nlintool
Hi, I built a function for use with nlinfit, see below: yhat = (b3.*x1.^b1.*x2.^b2.*x3.*x4.*x5.*x6); I'm happy with my results but was curious about nlintool. When I tried that I recieved the following error: ??? Error using ==> set Bad value for axes property: 'XLim' Values must be increasing and non-NaN.... 24 Jan 2010 22:32

scatter3
I have a ECG data and want to display them in clusters. Scatter3 is very good command for me to achieve my purpose. But, the markers are really big, so some data stays behind the other data and scatter3 does not accept a markersize parameter. My question is that how I can adjust markersize? Thanks in advance. ... 22 Jan 2010 10:37
