We don't do homework assignments on the list, but one answer
requires no loops and an understanding of the various ways R
uses vectors for indexing:

Subject: [R] Generating a matrix

I'm trying to write a function that will generate a NxN matrix
that has 
the value K on both diagonals, while the values outside the
diagonals 
(up and down) are 1's (for conflicting positions such as [4,5]
and [5,4] 
the larger value is written in the matrix). Basically, I'm
trying to 
replicate this matrix (where N = 8 and K = 5):

5  1  0  0  0  0  1  5
1  5  1  0  0  1  5  1
0  1  5  1  1  5  1  0
0  0  1  5  5  1  0  0
0  0  1  5  5  1  0  0
0  1  5  1  1  5  1  0
1  5  1  0  0  1  5  1
5  1  0  0  0  0  1  5

Any ideas? Thank you!
