DESCRIPTION
    For any matrix m, matfill(m, x) assigns to every element of m the

    x to the off-diagonal elements, y to the diagonal elements.

EXAMPLE
    ; mat A[3]; matfill(A, 2); print A
    mat [3] (3 elements, 3 nonzero):
	[0] = 2
	[1] = 2
	[2] = 2

    ; mat B[2, 1:2]; matfill(B,3,4); print B
    mat [2,1:2] (4 elements, 4 nonzero):
	[0,1] = 4
	[0,2] = 3
	[1,1] = 3
	[1,2] = 4
