I am trying to calculate a return based on two arrays, mval and mvalprevday.

Does anyone know how I can avoid getting many zeros. I basically think if I can tell Matlab to only calculate one result per row (I.e. column 1 in mval array * column 1 in mvalprevday array
rtn = mval / mvalprevday
rtn =
Columns 1 through 8
