Hello, I really need your help, I have to develop a program which allows to generate all the possible sub-matrices (30x15) of a mother matrix (220x15) with an exhaustive search for the purpose of antenna selection in a massive mimo system after all these sub antennas are generated it will be necessary to calculate the energy efficiency of each one to finally choose the optimal selection.
i tried this program, but it didn't generate me ALL possible submaters but only 220-30:
matrix = complex (rand (220.15), rand (220.15));
for row = 1: size (matrix, 1) -29
submatrix {row} = matrix (row: row + 29, :);
end
what should I do?
Thank you very much

i think in the first line, the rand functiuon should be rand(220,15), should be " , " rather than " . "

Yes , it's juste un false tap. Thank's
