I have A=2x2 Matrix,

But each element of Matrix; again have 1x4 Matrix(i.e.,A11(1x4)).

How can i read this elements.

for example:

A=[[1 2 3 4],[5 6 7 8];[11 12 13 14],[15 16 17 18]];

i.e.,

A{1,1}=[1 2 3 4];

A{1,2}=[5 6 7 8];

A{2,1}=[11 12 13 14];

A{2,2}=[15 16 17 18];

I want like this;

O{1,1}=[1 5; 11 15];

O{1,2}=[2 6; 12 16];

O{2,1}=[3 7; 13 17];

O{2,2}=[4 8; 14 18];

For this how can i write Program/Syntax...

在 MATLAB Online 中打开

This works:

% Original data:
A{1,1}=[1 2 3 4];
A{1,2}=[5 6 7 8];
A{2,1}=[11 12 13 14];
A{2,2}=[15 16 17 18];
% Create intermediate matrices:
O1 = cell2mat(A);
O2 = reshape(O1', [4 4])
% Create cell vector:
for k1 = 1:4
    O{k1} = O2(k1,:);
end
% Create cell output array:
O = reshape(O, [2 2])'
% View output: 
O{1,1}
O{1,2}
O{2,1}
O{2,2}
