function error
I've been writing it outside the function for debugging purposes, and once I had it working sufficiently and the way I wanted it, I put it into the function and it suddenly has problems. The problem is that when there are cross or dot products in the code it tells me the vectors aren't the same size, although they ar... 5 May 2010 22:42

operations on multiple files
I have the following 3 sets of files in .mat format X1 X2 X3 ...... I loaded all of them and i want to do the following t1=X1(:,2)./1000; t2=X2(:,2)./1000; t3=X3(:,2)./1000; x1=-X1(:,4)*0.001; x2=-X2(:,4)*0.001; x3=-X3(:,4)*0.001; tr11=t1-(x1./vr); tr21=t2-(x2./vr); ... 5 May 2010 20:29

Moving columns below other columns, in a matrix
Hi everyone! Say I have a 6x6 matrix - what is the easiest way of moving the rightmost 3 columns below the leftmost 3 columns, such that the matrix becomes 12x3? Thanks for any help! ... 5 May 2010 19:23

uniform random variable
Given 2 independent uniform random variables X,Y = U [0,1], consider the random variables Z = g (X,Y) for g (x,y) = sqrt (-2ln(x) ). cos(2piy)..This is the condition.So I need to go for matlab program as the analytic method is tough 1 - 10,000 uniformly distributed random samples for X and Y 2 - For each sample of ... 6 May 2010 16:30

variable dependency debugging tool
I have an idea for a debugging tool that would be very useful for me, I'm wondering if anyone has ever seen something like this: a program that determines the assignment dependencies of all variables in a given Matlab function. Ideally it would plot a graph of as well. The top of the plot would show all function inputs... 6 May 2010 00:54

HELP!!! lsqnonlin fitting problem
currently i'm workng on the minimization of: sum(x)sum(t)[Observations(x,t)-alfa-Ft-beta*exp(a*x)*Ft^2]^2 there're 2296 observations for x(41)*t(56) where a* is known, the optimization is performed with respect to alfa, beta, Ft, t varying. Ft as a factor value with t varying, should I estimate it as a param... 5 May 2010 20:29

Simulink: How to generate a sine wave using external source as frequency
I am trying to generate a sine wave whose frequency changes dynamically during simulation. The frequency should come as input to the sinewave block from another block. I would be grateful for any suggestion or help ... 6 May 2010 08:32
