:fortran_help: " SUBROUTINE CSPTRS( UPLO, N, NRHS, AP, IPIV, B, LDB, INFO )\n\n\
* Purpose\n\
* =======\n\
*\n\
* CSPTRS solves a system of linear equations A*X = B with a complex\n\
* symmetric matrix A stored in packed format using the factorization\n\
* A = U*D*U**T or A = L*D*L**T computed by CSPTRF.\n\
*\n\n\
* Arguments\n\
* =========\n\
*\n\
* UPLO (input) CHARACTER*1\n\
* Specifies whether the details of the factorization are stored\n\
* as an upper or lower triangular matrix.\n\
* = 'U': Upper triangular, form is A = U*D*U**T;\n\
* = 'L': Lower triangular, form is A = L*D*L**T.\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\
* AP (input) COMPLEX array, dimension (N*(N+1)/2)\n\
* The block diagonal matrix D and the multipliers used to\n\
* obtain the factor U or L as computed by CSPTRF, stored as a\n\
* packed triangular matrix.\n\
*\n\
* IPIV (input) INTEGER array, dimension (N)\n\
* Details of the interchanges and the block structure of D\n\
* as determined by CSPTRF.\n\
*\n\
* B (input/output) COMPLEX 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\
