MATLAB: How to split one big matrix in several matrices

mat2cellsplit matrices

I'm trying to split a 72×10 matrix in 10 24×3 matrices. The new matrices need to have in each line, 3 elements (which make 3 columns) of each column of the original 72×10 matrix. I tried to use mat2cell but always get the error "Input arguments, D1 through D2, must sum to each dimension of the input matrix size, [72 10]". I'm clearly not understanding something here.

cellfun(@(V) reshape(V, 24, 3), num2cell(a,1), 'uniform', 0)

A -your cell array [3 x 3].

Z = cellfun(@(x)reshape(x,1,1,[]),A,'un',0);
out = cell2mat(Z);

Try this

%-----------Your array--------------------------------------------------
Y1={num2cell(rand(16,107)),num2cell(rand(16,47)),num2cell(rand(16,147))};
Y2={num2cell(rand(16,107)),num2cell(rand(16,47)),num2cell(rand(16,147))};
Y3={num2cell(rand(16,107)),num2cell(rand(16,47)),num2cell(rand(16,147))};
Y4={num2cell(rand(16,107)),num2cell(rand(16,47)),num2cell(rand(16,147))};
Ycell={Y1,Y2,Y3,Y4}
%----------------Your code------------------------------------------------
n=numel(Ycell);
m=numel(Ycell{1});
M=cell(n,m);
for p=1:m
  for k=1:n
      M{k,p}=cell2mat(Ycell{k}{p});
  end
  [ii,jj]=size(M{k,p});
  a=cell2mat(M(1:n,p));
  b=reshape(a',jj,ii,[]);
  out{p}=nanmean(b,3)';
end
out
