:fortran_help: " SUBROUTINE ZGETRS( TRANS, N, NRHS, A, LDA, IPIV, B, LDB, INFO )\n\n\
* Purpose\n\
* =======\n\
*\n\
* ZGETRS solves a system of linear equations\n\
* A * X = B, A**T * X = B, or A**H * X = B\n\
* with a general N-by-N matrix A using the LU factorization computed\n\
* by ZGETRF.\n\
*\n\n\
* Arguments\n\
* =========\n\
*\n\
* TRANS (input) CHARACTER*1\n\
* Specifies the form of the system of equations:\n\
* = 'N': A * X = B (No transpose)\n\
* = 'T': A**T * X = B (Transpose)\n\
* = 'C': A**H * X = B (Conjugate transpose)\n\
*\n\
* N (input) INTEGER\n\
* The order of the matrix A. N >= 0.\n\
*\n\
* NRHS (input) INTEGER\n\
* The number of right hand sides, i.e., the number of columns\n\
* of the matrix B. NRHS >= 0.\n\
*\n\
* A (input) COMPLEX*16 array, dimension (LDA,N)\n\
* The factors L and U from the factorization A = P*L*U\n\
* as computed by ZGETRF.\n\
*\n\
* LDA (input) INTEGER\n\
* The leading dimension of the array A. LDA >= max(1,N).\n\
*\n\
* IPIV (input) INTEGER array, dimension (N)\n\
* The pivot indices from ZGETRF; for 1<=i<=N, row i of the\n\
* matrix was interchanged with row IPIV(i).\n\
*\n\
* B (input/output) COMPLEX*16 array, dimension (LDB,NRHS)\n\
* On entry, the right hand side matrix B.\n\
* On exit, the solution matrix X.\n\
*\n\
* LDB (input) INTEGER\n\
* The leading dimension of the array B. LDB >= max(1,N).\n\
*\n\
* INFO (output) INTEGER\n\
* = 0: successful exit\n\
* < 0: if INFO = -i, the i-th argument had an illegal value\n\
