Hi,

I have a 3D array, called A, that is 20*1000*30.

How can I convert the matrix A into 20 2D arrays, with size 1000*30, in which each array represents (i,:,:), where i is the ID of the array.

Best regards,

在 MATLAB Online 中打开

A=rand(20,1000,30);

for i = 1:20
   B{i} = squeeze(A(i,:,:));
end

B
B = 1×20 cell array
    {1000×30 double}    {1000×30 double}    {1000×30 double}    {1000×30 double}    {1000×30 double}    {1000×30 double}    {1000×30 double}    {1000×30 double}    {1000×30 double}    {1000×30 double}    {1000×30 double}    {1000×30 double}    {1000×30 double}    {1000×30 double}    {1000×30 double}    {1000×30 double}    {1000×30 double}    {1000×30 double}    {1000×30 double}    {1000×30 double}
