Function/Subroutine Documentation double precision function zla_gercond_c (character trans, integer n, complex*16, dimension( lda, * ) a, integer lda, complex*16, dimension( ldaf, * ) af, integer ldaf, integer, dimension( * ) ipiv, double precision, dimension( * ) c, logical capply, integer info, complex*16, dimension( * ) work, double precision, dimension( * ) rwork) ZLA_GERCOND_C computes the infinity norm condition number of op(A)*inv(diag(c)) for general matrices. Purpose: !> !> ZLA_GERCOND_C computes the infinity norm condition number of !> op(A) * inv(diag(C)) where C is a DOUBLE PRECISION vector. !> Parameters TRANS !> TRANS is CHARACTER*1 !> Specifies the form of the system of equations: !> = 'N': A * X = B (No transpose) !> = 'T': A**T * X = B (Transpose) !> = 'C': A**H * X = B (Conjugate Transpose = Transpose) !> N !> N is INTEGER !> The number of linear equations, i.e., the order of the !> matrix A. N >= 0. !> A !> A is COMPLEX*16 array, dimension (LDA,N) !> On entry, the N-by-N matrix A !> LDA !> LDA is INTEGER !> The leading dimension of the array A.
