I have two TV series. An array consists of 1 column and 5 rows. My B array consists of 50 columns and 5 rows. What I want here is to subtract the value of an array in row 1 column 1 from all elements of array B in row 1. And he continues this process in turn. I tried this code for this, but it doesn't work correctly. I will be glad if you help me.
for i = 1: 5
C = B (i, :) - A (i, 1);
end
