MatSolveTransAdd

Computes x = y + inv(trans(A)) b, given a factored matrix.

Synopsis

int MatSolveTransAdd(Mat mat,Vec b,Vec y,Vec x)
Collective on Mat and Vec

Input Parameters

mat - the factored matrix
b - the right-hand-side vector
y - the vector to be added to

Output Parameter

x -the result vector

Notes

The vectors b and x cannot be the same. I.e., one cannot call MatSolveTransAdd(A,x,y,x).

Most users should employ the simplified SLES interface for linear solvers instead of working directly with matrix algebra routines such as this. See, e.g., SLESCreate().
