Sets the matrix diagonal to values from the vector.

Syntax
C#
Visual Basic
public TMtx Diag([In] TVec Vec, int k);
Remarks

Sets the k-th diagonal of the calling matrix to values from from the Vec object. If k = 0 then the main diagonal matrix is set, if k < 0 then the k-th subdiagonal matrix is set and if k > 0 the then the k-th super diagonal is set. The matrix must be large enough to hold diagonal or an exception is raised.
