28NAME: @code{diag} - get diagonal part of a matrix
29@clindex dia
30@clindex vec
31@clindex csr
32@cindex diagonal matrix
33DESCRIPTION:
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
39TODO:
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
