PLASMA_sgeqrs - Compute a minimum-norm solution min || A*X - B || using the RQ factorization A = R*Q computed by PLASMA_sgeqrf.

Parameters:
[in] M The number of rows of the matrix A. M >= 0.
[in] N The number of columns of the matrix A. N >= M >= 0.
[in] NRHS The number of columns of B. NRHS >= 0.
[in,out] A Details of the QR factorization of the original matrix A as returned by PLASMA_sgeqrf.
[in] LDA The leading dimension of the array A. LDA >= M.
[in] T Auxiliary factorization data, computed by PLASMA_sgeqrf.
[in,out] B On entry, the m-by-nrhs right hand side matrix B. On exit, the n-by-nrhs solution matrix X.
[in] LDB The leading dimension of the array B. LDB >= max(1,N).
Returns:
Return values:
PLASMA_SUCCESS successful exit
<0 if -i, the i-th argument had an illegal value
