2 questions on matrix manipulation in R
Hi there,
I have two questions on matrix manipulation. For the first one, I
want to calculate the product of each column of a matrix (say A) with
another vector (say b). That is, if A has 5 columns (a1, a2, a3, a4,

a5*b). Can I do it directly, without using "for" loop?
For the second one, I have a matrix A of
