Hello
This may have been answered elsewhere, and I have looked on the web, but
nothing helps. I am trying to do the following:
X<-matrix(c(1:15),nrow=3,byrow=T)
Y<-matrix(c(2,4,6,8,10),ncol=1)
I need to sum the product of each row of X by the remaining j rows multiplied
by j y values (i.e s
Generally unambiguous questions get answered quickly. Perhaps other
readers are having the same difficulties I am experiencing. So let's
try to parse what you are asking:

Agree, it is ambiguous. Will try again
Suppose I have the following
X<-matrix(c(1:20),nrow=4,byrow=T), hence this is a 4 by 5 matrix
Y<-matrix(c(2,4,6,8),ncol=1), and this is a 4 by 1 vector, each value denote
y1, y2,y3, y4
Step 1 - write each row of X as a vector, so I have vectors t(x_
