Vectorizing nested for loops

Hello, I'm relatively new to Matlab and am having some difficulties vectorizing my code. Although I'm sure that the answer to my question exists somewhere, I confess that I haven't yet found it. Anyway, I'm trying to vectorize the following nested for loops: for i=2:rho {for|j=1:zDim {phi(i,j) = phi(1,j)/(1+i)}}

It's certainly just a rookie question, but I appreciate any advice.

bsxfun(@rdivide,phi,(1+(2:rho))')

here phi vector row

or use first row of 'phi' matrix

bsxfun(@rdivide,phi(1,:),(1+(2:rho))')

Thank you! I appreciate it.
