Lapack解决A * X = B'

Question

I would like to solve a linear system of the form A*X=B' , where B' is the transpose of B . A is a square matrix N-by-N and B is N-by-M . In lapack/lapacke, the function LAPACKE_dgesv (see an example here ) is used to solve systems of the form A*X=B , where B is treated as multiple right-hand side vectors. Is it possible to solve a system of the form A*X=B' without having to create a copy of B as Z=B' by re-ordering its values and then solve A*X=Z ?

Answer 1

To the very best of my knowledge, LAPACK offers no such functionality. You have to perform the transpose of B outside the calls to LAPACK.
