Friends,
If I have a {5x1 cell} string array, C with the following comma-separated content:
MSFT,2/1/2010 9:31,MSQ,2/20/2010,25,c,3.4,3.4,3.4,-0.01189
MSFT,2/1/2010 9:31,MSQ,2/20/2010,25,p,0,0,0,0.006922

i have a matrix of (1000  600)
I created a plot of size
x=-3to3
y=-5 to 5

Does anyone know of any companies hiring Matlab / Simulink developers in the Twin Cities metro area (Minneapolis/St.Paul and suburbs), Minnesota (MN)?:  I am a "world-class" expert at Matlab.   I also know C/C++, C#, GUI interfaces.  My e-mail address is josephamarks@yahoo.com.   ...

I have a problem I can't solve it.
I have to vectors such as
A=[5;4;3;2;1];
B=[6;7;8;9;10];

I've been struggling with this problem for a while and I can't seem to find out much about it. What I have are lots of 3*3 matrices which represent linear operators. I'm interested in the properties of these linear operators and have thus decomposed them into eigenvectors and ...

Please what commande i must to use in matlab for integrate my function: dg/dt = f(t)
thank you to orient me

Background information:
I have two samples, X1 and X2. X1 and X2 are categorical (2 or 3 cases). I want to use chi-square test to test whether X1 and X2 are drawn from  the same underlying distribution.  
Question:
Does matlab have a function for chi-square test for two samples, ...

Hi People,
I'm trying to create a decimal to binary function for an array input
but it seems that my output is always wrong, I believe it has
something to do with the loop.

I am trying to display the intersection of cylinders in Matlab. Some example of the shapes I am trying to render could be found here: http://local.wasp.uwa.edu.au/~pbourke/geometry/cylinders/
Is there anyway I could do this in Matlab?
Thanks a lot,
Babak.

I am looking for a way to slice along one dimension and copy along all
others. I am looping through the fields of a structure. The data for
each field is a matrix with 2 or more dimensions. Along the first
dimension, all have the same size, but the other dimensions differ. I

Using this function "[XL,YL,XS,YS,B,PC,MSE,stats] = PLSREGRESS(x,y,2,'CV',5)", in that number of cross-validation is five, I would expect to get five different outputs for each output. For example I would like to extract these outputs [XL1, XL2...., and XL5], [YL1, YL2...., and ...

Given vectors x and y each with N elements, I want to create an N element structure s with fields s.x and s.y. I can do this by
for ii=1:N,
s(ii).x=x(ii);
s(ii).y=y(ii);

Is there a way to simply return the number of elements in an array that is less than a given number. I'm currently doing it the way I would in C but I know matlab probably has a better way!
       for k=1:length(x_coords)
           if x_coords(k) < thresh

I'm trying to make my program as a stand-alone executable using the Matlab Compiler. I realize that any PC I use to run the file must have the MCR installed on it. When i click "Add MCR" when building the project, it adds a file called MCRInstaller.exe, but i cant find it in the ...

I have a matrix N*N*N, I want to find the minimum mean value of a n*n*n sub-matrix within the large one.
How should i go through the whole matrix with the small n*n*n cubic, I am thinking to use:
[X,Y,Z] = meshgrid(A, -1:1,-1:1,-1:1);
then run through the matrix to calculate
