dividing a matrix into equal submatrices

Hello all,

I need to take a matrix that is one column of non integers and divide it into 10 equal length matrices that are 1/10 of the original, but still one column, for analysis. mat2cell doesn't work on non integers and nothing I have been searching in has given an answer. I'm fairly new to MATLAB, so please be kind if this is a fairly simple request. Any help would be awesome.

Thanks, Matt

I assume that your vector, x, is n-by-1 where n is divisible by 10.

Try

xIntoTenPieces = reshape(x,[],10);

which produces a matrix, each column is is 1/10 of the original vector x. You can access the kth column with the syntax

xIntoTenPieces(:,k)

Exactly what I wanted to do. Thanks so much!

My pleasure!

mat2cell() works fine for any numeric array.

L = size(x,1);
L10 = L / 10;
mat2cell(x, repmat(L10,1,10), 1)
