Splitting n by 1 matrix

Hi, I have n by 1 matrix, I want to splitt this matrix into systematically into several smaller matrices of the same dimension. For example let A=transpose([1:1:12552), I want to make other matrices of (24 by 1) from the A. Is there a short command I can use? I have tried 'mat2cell' function but it returns error. Is there something am missing?

A = transpose(1:12552);
C = num2cell(reshape(A,24,[]),1)

C = 1×523 cell array

You can eaily access the content of the cell array C using indexing, e.g. the second cell:

C{2}

ans = 24×1

25 26 27 28 29 30 31 32 33 34

Thank you so much, it has worked perfectly well. Is there a fucntion that I can use to calculate mean of each submatrix within C, so as to end up with 523 by 1 matrix?

[Dyuman Joshi]

A = transpose(1:12552);
C = num2cell(reshape(A,24,[]),1);
Cm=cellfun(@mean,C')

Cm = 523×1

" Is there a fucntion that I can use to calculate mean of each submatrix within C, so as to end up with 523 by 1 matrix?"

The simple and efficient MATLAB approach would avoid the cell array:

A = transpose(1:12552);
B = mean(reshape(A,24,[]),1).'

B = 523×1

12.5000 36.5000 60.5000 84.5000 108.5000 132.5000 156.5000 180.5000 204.5000 228.5000
