Purpose:

      !>
      !> CLARCM performs a very simple matrix-matrix multiplication:
      !>          C := A * B,
      !> where A is M by M and real; B is M by N and complex;
      !> C is M by N and complex.
      !>

Parameters

  [in]

  M

      !>          M is INTEGER
      !>          The number of rows of the matrix A and of the matrix C.
      !>          M >= 0.
      !>

  [in]

  N

      !>          N is INTEGER
      !>          The number of columns and rows of the matrix B and
      !>          the number of columns of the matrix C.
      !>          N >= 0.
      !>

  [in]

  A

      !>          A is REAL array, dimension (LDA, M)
      !>          On entry, A contains the M by M matrix A.
      !>

  [in]

  LDA

      !>          LDA is INTEGER

      !>

  [in]

  B

      !>          B is COMPLEX array, dimension (LDB, N)
      !>          On entry, B contains the M by N matrix B.
      !>

  [in]

  LDB

      !>          LDB is INTEGER
      !>          The leading dimension of the array B. LDB >=max(1,M).
      !>

  [out]

  C

      !>          C is COMPLEX array, dimension (LDC, N)
      !>          On exit, C contains the M by N matrix C.
      !>

  [in]

  LDC

      !>          LDC is INTEGER
      !>          The leading dimension of the array C. LDC >=max(1,M).
      !>

  [out]
