Matrix into Sub matrix of length 8

Suppose I have a matrix like this A = [1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24] (Length of a Matrix is always multiple of 8). I want to break it into sub matrices of length 8. I use reshape function but it does not work. Needs your help.

What does "does not work" mean, precisely? Show your work, error received...or what you expected instead.

In general breaking into submatrices by creating new variables isn't productive manner in which to use, Matlab; instead reference subsets of an array as needed for which reshape can be quite useful...or, depending on what it is that is actually being done, blockproc in the image processing toolbox can be the ticket or various other specialty routines can be the answer--each depending on just what the actual end need may be...

What did you try for reshape? Did you try reshape(A, [], 8)?

A=[1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24];
a8 = reshape(A, [], 8)
% For example, to get 2nd subarray of 8 specify group as 1st index and : as second index.
out = a8(2,:)

Silmilar question answer is here, in your case minor modification is required. Here it is

A=[1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24];
n=length(A)/8;
C=num2cell(reshape(A,length(A)/n,n),1);

Access the subarrays in C{1}, C(2)..so on..
