+/* ZHERK performs one of the hermitian rank k operations */
+
+/* C := alpha*A*conjg( A' ) + beta*C, */
+
+/* or */
+
+/* C := alpha*conjg( A' )*A + beta*C, */
+
+/* where alpha and beta are real scalars, C is an n by n hermitian */
+/* matrix and A is an n by k matrix in the first case and a k by n */
+/* matrix in the second case. */
+
+/* Arguments */
+/* ========== */
+
+/* UPLO - CHARACTER*1. */
+/* On entry, UPLO specifies whether the upper or lower */
+/* triangular part of the array C is to be referenced as */
+/* follows: */
+
+/* UPLO = 'U' or 'u' Only the upper triangular part of C */
+/* is to be referenced. */
+
+/* UPLO = 'L' or 'l' Only the lower triangular part of C */
+/* is to be referenced. */
+
+/* Unchanged on exit. */
+
+/* TRANS - CHARACTER*1. */
+/* On entry, TRANS specifies the operation to be performed as */
+/* follows: */
+
+/* TRANS = 'N' or 'n' C := alpha*A*conjg( A' ) + beta*C. */
+
+/* TRANS = 'C' or 'c' C := alpha*conjg( A' )*A + beta*C. */
+
+/* Unchanged on exit. */
+
+/* N - INTEGER. */
+/* On entry, N specifies the order of the matrix C. N must be */
+/* at least zero. */
+/* Unchanged on exit. */
+
+/* K - INTEGER. */
+/* On entry with TRANS = 'N' or 'n', K specifies the number */
+/* of columns of the matrix A, and on entry with */
+/* TRANS = 'C' or 'c', K specifies the number of rows of the */
+/* matrix A. K must be at least zero. */
+/* Unchanged on exit. */
+
+/* ALPHA - DOUBLE PRECISION . */
+/* On entry, ALPHA specifies the scalar alpha. */
+/* Unchanged on exit. */
+
+/* A - COMPLEX*16 array of DIMENSION ( LDA, ka ), where ka is */
+/* k when TRANS = 'N' or 'n', and is n otherwise. */
+/* Before entry with TRANS = 'N' or 'n', the leading n by k */
+/* part of the array A must contain the matrix A, otherwise */
+/* the leading k by n part of the array A must contain the */
+/* matrix A. */
+/* Unchanged on exit. */
+
+/* LDA - INTEGER. */
+/* On entry, LDA specifies the first dimension of A as declared */
+/* in the calling (sub) program. When TRANS = 'N' or 'n' */
+/* then LDA must be at least max( 1, n ), otherwise LDA must */
+/* be at least max( 1, k ). */
+/* Unchanged on exit. */
+
+/* BETA - DOUBLE PRECISION. */
+/* On entry, BETA specifies the scalar beta. */
+/* Unchanged on exit. */
+
+/* C - COMPLEX*16 array of DIMENSION ( LDC, n ). */
+/* Before entry with UPLO = 'U' or 'u', the leading n by n */
+/* upper triangular part of the array C must contain the upper */
+/* triangular part of the hermitian matrix and the strictly */
+/* lower triangular part of C is not referenced. On exit, the */
+/* upper triangular part of the array C is overwritten by the */
+/* upper triangular part of the updated matrix. */
+/* Before entry with UPLO = 'L' or 'l', the leading n by n */
+/* lower triangular part of the array C must contain the lower */
+/* triangular part of the hermitian matrix and the strictly */
+/* upper triangular part of C is not referenced. On exit, the */
+/* lower triangular part of the array C is overwritten by the */
+/* lower triangular part of the updated matrix. */
+/* Note that the imaginary parts of the diagonal elements need */
+/* not be set, they are assumed to be zero, and on exit they */
+/* are set to zero. */
+
+/* LDC - INTEGER. */
+/* On entry, LDC specifies the first dimension of C as declared */
+/* in the calling (sub) program. LDC must be at least */
+/* max( 1, n ). */
