Hi everyone.
I'm using matrix product such as :
#Generate some data
NCols = 5
NRows = 5
A = matrix(runif(NCols*NRows), ncol=NCols)
B = matrix(runif(NCols*NRows), ncol=NCols)
#First calculation
R = A%*%B
for(i in 1:100)
{
R = R%*%B
}
I would like to know if it was possible to avoid the loop by using something
like mapply or anything else.
Tx in advance,
Phil
