All depends upon how you want to reshape your vector,

I'm assuming you have a vector with dimension n*m x 1 that you want to transform into a n x m matrix

If this is correct, you can use the reshape command (type 'help reshape' into the Command Window for further info) which in your case would be

A = reshape(your_vector,m,n);

I dont have matlab on this PC so Im not sure if it allocates columnwise or rowwise, but if the above doesnt work, then it should be

A = reshape(your_vector,n,m)

Alternatively you would always script a simple piece of code to do it

(either in the Command Window or a simple m-file)

for i = 1:1:10

A(:,i) = your_vector(100*(i-1) + 1 : 100*i);

end

you can preallocate the matrix A first if you want to (i.e. above the for statement include A = zeros(100,10)

Hope this helps,
