I have a matrix A that has the format 150000x8 and a vector B of the format 1x8. I want to create a function that divide every value in the first column of the matrix by the first value from the matrix, the 2nd column with the second value and so on. Is there anyway to write this in one line or should i code it individually for each column?

A = randn(150000,8);
B = randn(1,8);
C = A./B; % this should be all you have to do*
size(C)
ans = 1×2
150000 8
*In older versions of MATLAB, before R2016b, you would have to do something like this:
C = A./repmat(B,size(A,1),1);
size(C)
ans = 1×2
150000 8
