Forcing display output from cellarray
You can convert the cell array into a character matrix using char(c) before you display it. This will pad the shorter strings with with white spaces. ... 16 Apr 2010 21:47

Recommendations for data structure for multivariate time series
Hi All, I would like to get ideas on a data structure for storing multivariate time series type data. Background: I have n experimental conditions with m environmental parameters. My coworkers are interested in examining how i possible product versions behave under the above conditions measuring j variables w... 16 Apr 2010 21:46

i create program using matlab GUI, the purpose is to show live video from webcam... my GUI has two different axis, one to display video using preview(vid,hImage); and the other one to display histogram. but the preview appear randomly between axes1 and axes2. does anybody know how to control video preview ? I tried ... 13 May 2010 19:22

ofdma subcarrier Carrier to noise ratio
Hi i want to find channel fading gain and then CINR for a carrier frequency where total data sub carrier are 720 sn_r=11db ch=rayleighchan; sb_carrier=360000000;%360mHz t= [0:.01:1]; s_1 = sin(2*pi*sb_carrier*t) s... 16 Apr 2010 20:40

alternating ylabels
does anyone know how to make a loop where two different ylabels are displayed every other turn? (a turn would be denoted as a click and move of a checker piece.) this is what I have so far and cannot find where the "index exceeds the matrix dimensions." this is for a checkers game project and if you have any informa... 16 Apr 2010 19:33

notch filter problem
Hi I try to design a 60Hz digital notch filter with 120kHz sampling rate. The z transform function is: hd= (0.9986 z^2 - 1.997 z + 0.9986)/( z^2 - 1.997 z + 0.9971) After that I run following: t=0:ts:0.09 in=sin(60*2*pi*t); lsim(hd,'b',in,t); In time domain, it shows perfect result that 60Hz signal gets rem... 16 Apr 2010 18:26

Warning: Explicit integral could not be found.
I tried the following M-file: clc clear all syms x f=(x^2/exp(x^2/2) - 1/exp(x^2/2) + 4)^2; a=-3; b=3; Integral=real(double(int(f,a,b))); fprintf('Integral value: %5.3f',Integral); disp(' ') Even though the condition "Warning: Explicit integral could not be found" is printed on the screen, the calculatio... 17 Apr 2010 01:02

Identifying workspaces
How about this: if isempty(evalin('caller','mfilename')) %from command line else %from function or script end It will let you see if the caller is the command line or something else. --- I'm also a fan of Python, but when in Rome... I handle this problem "the Matlab way", so I make some effort t... 16 Apr 2010 18:26

pass in the name of the output file
Hi, I have a function file say fun(NL). It does something and saves the data in a file say NLxx.out.mat. Before I call the function with a specific value of NL (NL=08) I go into the function file and change the file name to NL08.out.mat. Again before I call fun(04) I go and edit the function file so the output is... 18 Apr 2010 08:39
