DESCRIPTION:
34
This function get the diagonal part of a matrix.
35
@example
36
csr<Float> a;
37
dia<Float> d = diag(a);
38
@end example
39
TODO:
40
Build a csr matrix from a diagonal one or from a vector:
41
@example
42
dia<Float> d;
43
csr<Float> a = diag(d);
44
vec<Float> u;
45
csr<Float> b = diag(u);
46
@end example
