Q: How to subtract a vector from each row of a matrix Solved, solution in comments, thank you.
A 14x14 matrix named "RET", a 1x14 vector named "R". How do I make a new matrix "Si" such that each row of "Si" is each row of "Ret" subtracted by "R"?
I've tried
Si=Ret-R

And
Si=Do[Ret[[i]]-R,{i,14}]

Neither worked.
