## MA02PD

### Compute the number of zero rows and zero columns of a real matrix

[Specification] [Arguments] [Method] [References] [Comments] [Example]

Purpose

      To compute the number of zero rows and zero columns of a real
      matrix.

Specification

          SUBROUTINE MA02PD( M, N, A, LDA, NZR, NZC )
    C     .. Scalar Arguments ..
          INTEGER            LDA, M, N, NZC, NZR
    C     .. Array Arguments ..
          DOUBLE PRECISION   A( LDA, * )

Arguments

Input/Output Parameters

      M       (input) INTEGER
              The number of rows of the matrix A.  M >= 0.

      N       (input) INTEGER
              The number of columns of the matrix A.  N >= 0.

      A       (input) DOUBLE PRECISION array, dimension (LDA,N)
              The leading M-by-N part of this array must contain the
              matrix A.

      LDA     INTEGER
              The leading dimension of the array A.  LDA >= max(1,M).

      NZR     (output) INTEGER
              The number of zero rows of the matrix A.

      NZC     (output) INTEGER
              The number of zero columns of the matrix A.
