         February 29, 1992   
  
  
      Purpose   
      =======   
  
      DLACPY copies all or part of a two-dimensional matrix A to another   
      matrix B.   
  
      Arguments   
      =========   
  
      UPLO    (input) CHARACTER*1   
              Specifies the part of the matrix A to be copied to B.   
              = 'U':      Upper triangular part   
              = 'L':      Lower triangular part   
              Otherwise:  All of the matrix A   
  
      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 m by n matrix A.  If UPLO = 'U', only the upper triangle   
              or trapezoid is accessed; if UPLO = 'L', only the lower   
              triangle or trapezoid is accessed.   
  
      LDA     (input) INTEGER   
              The leading dimension of the array A.  LDA >= max(1,M).   
  
      B       (output) DOUBLE PRECISION array, dimension (LDB,N)   
              On exit, B = A in the locations specified by UPLO.   
  
      LDB     (input) INTEGER   
              The leading dimension of the array B.  LDB >= max(1,M).
