/*  Purpose */
/*  ======= */

/*  CTRMM  performs one of the matrix-matrix operations */

/*     B := alpha*op( A )*B,   or   B := alpha*B*op( A ) */

/*  where  alpha  is a scalar,  B  is an m by n matrix,  A  is a unit, or */
/*  non-unit,  upper or lower triangular matrix  and  op( A )  is one  of */

/*     op( A ) = A   or   op( A ) = A'   or   op( A ) = conjg( A' ). */

/*  Arguments */
/*  ========== */

/*  SIDE   - CHARACTER*1. */
/*           On entry,  SIDE specifies whether  op( A ) multiplies B from */
/*           the left or right as follows: */

/*              SIDE = 'L' or 'l'   B := alpha*op( A )*B. */

/*              SIDE = 'R' or 'r'   B := alpha*B*op( A ). */

/*           Unchanged on exit. */

/*  UPLO   - CHARACTER*1. */
/*           On entry, UPLO specifies whether the matrix A is an upper or */
/*           lower triangular matrix as follows: */

/*              UPLO = 'U' or 'u'   A is an upper triangular matrix. */

/*              UPLO = 'L' or 'l'   A is a lower triangular matrix. */

/*           Unchanged on exit. */

/*  TRANSA - CHARACTER*1. */
/*           On entry, TRANSA specifies the form of op( A ) to be used in */
/*           the matrix multiplication as follows: */

/*              TRANSA = 'N' or 'n'   op( A ) = A. */

/*              TRANSA = 'T' or 't'   op( A ) = A'. */

/*              TRANSA = 'C' or 'c'   op( A ) = conjg( A' ). */

/*           Unchanged on exit. */

/*  DIAG   - CHARACTER*1. */
/*           On entry, DIAG specifies whether or not A is unit triangular */
/*           as follows: */

/*              DIAG = 'U' or 'u'   A is assumed to be unit triangular. */

/*              DIAG = 'N' or 'n'   A is not assumed to be unit */
/*                                  triangular. */

/*           Unchanged on exit. */

/*  M      - INTEGER. */
/*           On entry, M specifies the number of rows of B. M must be at */
/*           least zero. */
/*           Unchanged on exit. */

/*  N      - INTEGER. */
/*           On entry, N specifies the number of columns of B.  N must be */
/*           at least zero. */
/*           Unchanged on exit. */

/*  ALPHA  - COMPLEX         . */
/*           On entry,  ALPHA specifies the scalar  alpha. When  alpha is */
/*           zero then  A is not referenced and  B need not be set before */
/*           entry. */
/*           Unchanged on exit. */

/*  A      - COMPLEX          array of DIMENSION ( LDA, k ), where k is m */
/*           when  SIDE = 'L' or 'l'  and is  n  when  SIDE = 'R' or 'r'. */
/*           Before entry  with  UPLO = 'U' or 'u',  the  leading  k by k */
/*           upper triangular part of the array  A must contain the upper */
/*           triangular matrix  and the strictly lower triangular part of */
/*           A is not referenced. */
/*           Before entry  with  UPLO = 'L' or 'l',  the  leading  k by k */
/*           lower triangular part of the array  A must contain the lower */
/*           triangular matrix  and the strictly upper triangular part of */
/*           A is not referenced. */
/*           Note that when  DIAG = 'U' or 'u',  the diagonal elements of */
/*           A  are not referenced either,  but are assumed to be  unity. */
/*           Unchanged on exit. */

/*  LDA    - INTEGER. */
/*           On entry, LDA specifies the first dimension of A as declared */
/*           in the calling (sub) program.  When  SIDE = 'L' or 'l'  then */
/*           LDA  must be at least  max( 1, m ),  when  SIDE = 'R' or 'r' */
/*           then LDA must be at least max( 1, n ). */
/*           Unchanged on exit. */

/*  B      - COMPLEX          array of DIMENSION ( LDB, n ). */
/*           Before entry,  the leading  m by n part of the array  B must */
/*           contain the matrix  B,  and  on exit  is overwritten  by the */
/*           transformed matrix. */

/*  LDB    - INTEGER. */
/*           On entry, LDB specifies the first dimension of B as declared */
/*           in  the  calling  (sub)  program.   LDB  must  be  at  least */
/*           max( 1, m ). */
/*           Unchanged on exit. */
