float PLASMA_clansy ( PLASMA_enum  norm,
PLASMA_enum  uplo,
int  N,
PLASMA_Complex32_t *  A,
int  LDA,
float *  work 
)

PLASMA_clansy returns the value

clansy = ( 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] uplo = PlasmaUpper: Upper triangle of A is stored; = PlasmaLower: Lower triangle of A is stored.
[in] N The number of columns/rows of the matrix A. N >= 0. When N = 0, the returned value is set to zero.
[in] A The N-by-N matrix A.
[in] LDA The leading dimension of the array A. LDA >= max(1,N).
[in] work float precision array of dimension PLASMA_SIZE is PLASMA_STATIC_SCHEDULING is used, and NULL otherwise.
Returns:
Return values:
the norm described above.
