merging two matrices (cell matrices)

Hi,

I have two Matrices of dimension A=(63x181) and B=(63x181) I wish to get a matrix 'C' which has its first column from A and 2nd column from B. Then 3rd column from A and 4rth Column from B and so on till the end.

So, Matrix C will have 63 rows and 362 columns (181*2). Order of rown should remain the same.

I am using this code but it only writes one row. Doesn't write the full 63 rows of each column.

for m=2:2:362;
n=m-1;
x=m/2;
C{:,n}=A{:,x};
C{:,m}=B{:,x};
end;

Your help will be highly appreciated. I wonder if there is any builtin function like Cat(), vertcat() to for this.

Regards

AMD.

The following would be one way if I interpret well your question (which is not completely clear):

 C = reshape([A;B], size(A,1), []) ;

It creates a matrix with the following structure:

 C = [A(:,1),B(:,1),A(:,2),B(:,2), ..., A(:,181),B(:,181)]

C = zeros(size(A).*[1 2]);
C(:,1:2:end) = A;
C(:,2:2:end) = B;
