# KSPMatSolveTranspose
Solves a linear system with the transposed matrix with multiple right-hand sides stored as a `MATDENSE`. Unlike `KSPSolveTranspose()`, `B` and `X` must be different matrices and the transposed matrix cannot be assembled explicitly for the user. 
## Synopsis
```
#include "petscksp.h" 
#include "petscmat.h" 
PetscErrorCode KSPMatSolveTranspose(KSP ksp, Mat B, Mat X)
```

## Input Parameters

- ***ksp -*** iterative context
- ***B -*** block of right-hand sides



## Output Parameter

- ***X -*** block of solutions



## Notes
This is a stripped-down version of `KSPSolveTranspose()`, which only handles `-ksp_view`, `-ksp_converged_reason`, `-ksp_converged_rate`, and `-ksp_view_final_residual`.
