how to separate the real and imaginary parts inside a cell

i have a cell of size 1X2. inside the cell there are 2 matrices of size 32X32. i want to separate the real and imaginary of both the matrices that is inside the cell the two matrices should be 32X32X2. and finally i want the size to be 2X32X32X2. How to do it.

Hi Anusaya,

Can you please share an example of the cell and the matrices for better understanding?

[ANUSAYA SWAIN]

like cell size is 1X2. inside the cell two matrices of size 32X32 are there. those matrices are complex double. Next i want to separate the real and imaginary parts of those two matrices and make the matrices size as 32X32X2. now the cell has two matrices of size 32X32X2. Next i want to convert that cell to matrix of final size 2X32X32X2.

Maybe this ?

% create dummy data
n = 32;

for k = 1:2
    cellarray{k} = k*ones(n,n)*(1+1i*5);
end

% process it 
for k = 1:numel(cellarray)
    out(k,:,:,1) = real(cellarray{k}); % extract / store real matrix
    out(k,:,:,2) = imag(cellarray{k}); % extract / store imag matrix
end

Hi,

Please find the below code for the same:

% Assuming 'cellArray' is your 1x2 cell array containing two 32x32 matrices and assigining with random values

% You may use your values

cellArray = {rand(32) + 1i*rand(32), rand(32) + 1i*rand(32)};

result = zeros(2, 32, 32, 2); % Final result will be stored in this

for i = 1:2

matrix = cellArray{i};

realPart = real(matrix);

imagPart = imag(matrix);

combinedMatrix = cat(3, realPart, imagPart); % Combining them into a 32x32x2 matrix

result(i, :, :, :) = combinedMatrix;

end

disp(result);

Hope this helps!
