MatCreateADA
Creates a matrix M=A^T D1 A + D2.
Synopsis
#include "mat.h"
int MatCreateADA(Mat mat,Vec D1, Vec D2, Mat *J)
Collective on matrix
Input Parameters
| mat | - matrix of arbitrary type
|
| D1 | - A vector
|
| D2 | - A vector
|
Output Parameters
J -New matrix whose operations are defined in terms of mat, D1, and D2.
Notes
The user provides the input data and is responsible for destroying
this data after matrix J has been destroyed.
The operation MatMult(A,D2,D1) must be well defined.
Before calling the operation MatGetDiagonal(), the function
MatADAComputeDiagonal() must be called. The matrices A and D1 must
be the same during calls to MatADAComputeDiagonal() and
MatGetDiagonal().
