Synopsis

#include "slepcds.h" 
PetscErrorCode DSGetDimensions(DS ds,PetscInt *n,PetscInt *m,PetscInt *l,PetscInt *k,PetscInt *t)
Not Collective

Input Parameter

ds  - the direct solver context

Output Parameter

n  - the current size
m  - the current column size (only for DSSVD)
l  - number of locked (inactive) leading columns
k  - intermediate dimension (e.g., position of arrow)
t  - truncated length

Note

The t parameter makes sense only if DSTruncate() has been called. Otherwise its value equals n.
