How to divide matrix into sub matrix

Question

0 个投票

I have the matrix: time=0:0.05:8; and I'm trying to divide it into multiple matrices of 4. I tried using:

TIME=mat2cell(time,1,4) but i don't know what I'm doing wrong.

Can you elaborate? I'm not following "multiple matrices of 4." What are you wanting to do with the sub-matrices?

First, this is easier if you create ‘time’ so the length is an integer multiple of 4.

Then, creating the cell array is straightforward:

time=0:0.05:8-0.05;
TIME=mat2cell(time,1, fix(numel(time)/4)*ones(1,4))

This creates ‘TIME’ as 4 (1x40) cell arrays, because ‘fix(numel(time)/4)’ for this ‘time’ vector is 40.

The row and column dimensions of the arguments to mat2cell must equal the row and column dimensions of the argument array.
