Quantlet:		diagrv
Description:		replaces the diagonal of x by v

Usage:	`y = diagrv(x,v)`
Input:
	`x`	n x p x d1 x d2 ... array of n x p matrices
	`v`	np x 1 vector, where np is min(n, p)
Output:
	`y`	n x p x d1 x d2 ... array of n x p matrices

Example:

library("multi") diagrv( diag( #(1, 2) ), 5|5 )

Result:

Contents of y
[1,]        5        0
[2,]        0        5

Example:

library("multi") diagrv( matrix(3, 2, 2), 5|5 )

Result:

Contents of y
[,,1,1,1,1,1,1]
[1,]        5        1
[2,]        1        5
