Function Documentation

__attribute__ ( (weak)  )

Calculates max, one, infinity or Frobenius norm of a given matrix.

Parameters
[in]norm
  • PlasmaMaxNorm: Max norm
  • PlasmaOneNorm: One norm
  • PlasmaInfNorm: Infinity norm
  • PlasmaFrobeniusNorm: Frobenius norm
[in]mThe number of rows of the matrix A. m >= 0. When m = 0, the returned value is set to zero.
[in]nThe number of columns of the matrix A. n >= 0. When n = 0, the returned value is set to zero.
[in]AThe m-by-n matrix A.
[in]ldaThe leading dimension of the array A. lda >= max(1,m).
[in]workThe auxiliary work array.
[out]valueThe specified norm of the given matrix A
