PetscErrorCode MatOrthColumns(Mat A, MatOrthType type, MatOrthForm form, Mat *Q_new, Mat *S_new)Collective on Mat
| A | - the matrix whose columns will be orthonormalized | |
| type | - the algorithm used for orthonormalization (one of MAT_ORTH_NONE, MAT_ORTH_GS, MAT_ORTH_CHOLESKY, MAT_ORTH_CHOLESKY_EXPLICIT) | |
| form | - specify whether Q is computed explicitly or as an implicit product of A and S (one of MAT_ORTH_FORM_IMPLICIT, MAT_ORTH_FORM_EXPLICIT) |
| Q_new | - (optional) the Q factor of the same size as A | |
| S_new | - (optional) the inverse of the R factor |
