For example, if I have matrix: A = [5, 9, 25, 2, 21, 36];

and I want matrices:

B = [5, 9, 25]; C = [2, 21, 36];

What command do I need to use to split it into two halves? I originally have a matrix of size 1x100001 so I can't manually make two matrices like what I did here lol

在 MATLAB Online 中打开

n = ceil(numel(A)/2);
B = A(1:n)
C = A(n+1:end);

n = ceil(numel(A)/2);
BandC = mat2cell(A(:)',1,[n,numel(A)-n]);
