Hi all,

I would appreciate your help on the following problem:

assume that we have a matrix m with dimensions (RxC) and a vector s 
with dimensions (Rx1). Now what I want is to create another matrix Q

If m[[i,j]]>s[[i]], then Q=(m[[i,j]]-s[[i]])/s[[i]], for {i,1,R},{j,1,C}

I'm sure there must be an elegant and fast way to do that.

Best Regards
