MatCreateNormalHermitian#

Creates a new matrix object MATNORMALHERMITIAN that behaves like (A*)’*A.

Synopsis#

#include "petscmat.h" 
PetscErrorCode MatCreateNormalHermitian(Mat A, Mat *N)

Collective

Input Parameter#

  • A - the (possibly rectangular complex) matrix

Output Parameter#

  • N - the matrix that represents (A*)’*A

Note#

The product (A*)’A is NOT actually formed! Rather the new matrix object performs the matrix-vector product, MatMult(), by first multiplying by A and then (A)’
