  PLASMA_clange returns the value clange = ( max(abs(A(i,j))), NORM = PlasmaMaxNorm ( ( norm1(A), NORM = PlasmaOneNorm ( ( normI(A), NORM = PlasmaInfNorm ( ( normF(A), NORM = PlasmaFrobeniusNorm where norm1 denotes the one norm of a matrix (maximum column sum), normI denotes the infinity norm of a matrix (maximum row sum) and normF denotes the Frobenius norm of a matrix (square root of sum of squares). Note that max(abs(A(i,j))) is not a consistent matrix norm. Parameters
  [in] | norm | = PlasmaMaxNorm: Max norm = PlasmaOneNorm: One norm = PlasmaInfNorm: Infinity norm = PlasmaFrobeniusNorm: Frobenius norm
  [in] | M | The number of rows of the matrix A. M >= 0. When M = 0, the returned value is set to zero.
  [in] | N | The number of columns of the matrix A. N >= 0. When N = 0, the returned value is set to zero.
  [in] | A | The M-by-N matrix A.
  [in] | LDA | The leading dimension of the array A. LDA >= max(1,M).
  [in] | work | real array of dimension (MAX(1,LWORK)), where LWORK >= M when NORM = PlasmaInfNorm; otherwise, WORK is not referenced.
  Returns Return values
  the | norm described above.
