Dear David, Ted, Kjetil, Petr,
thank you, you guys did a great job, I'll use your ideas in the future
for sure.
After I sent the question I figured a way, see below.
x <- 1:81
b <- 1:3
Q <- matrix(x,9,9)
result <- matrix(matrix(colSums(matrix(t(Q),3)),,3,TRUE) %*% b,3,3)
I hope there is no er

Dear list-members,
I have a 9-by-9 matrix lets call it A with first row a11, a12,
a13,..., a19 etc.
I also have a vector of length 3 (B).
I want to construct a matrix of size 3x3 in the following way:
- divide matrix A to 9 3x3 blocks
- first

Dear list-members,
I have a 9-by-9 matrix lets call it A with first row a11, a12, a13,...,
a19 etc.
I also have a vector of length 3 (B).
I want to construct a matrix of size 3x3 in the following way:
- divide matrix A to 9 3x3 blocks
- first is
a11, a12, a13
a21, a22, a23
