BLAS Standard error handler F_BLASERROR

Name F_BLASERROR

BLAS Standard error handler

Purpose F_BLASERROR is an error handler for the BLAS Standard routines. It is

called by a BLAS Standard routine when an input parameter has an invalid

value. F_BLASERROR prints an error message and execution stops. You may

supply a version of F_BLASERROR that modiﬁes the action performed.

The following values of arguments are invalid for BLAS Standard routines and

are ﬂagged by the error handling routine:

• Any value of the operator arguments whose meaning is not speciﬁed in the

language-dependent section of the BLAS Standard

•

incw = 0 or incx = 0 or incy = 0 or incz = 0

• lda, ldb, ldc, or ldt < 1

• lda < m if the matrix is an m-by-n general matrix

• lda < n if the matrix is an n-by-n square, symmetric, or triangular matrix

• lda < kl + ku + 1, if the matrix is an m-by-n general band matrix

• lda < k + 1, if the matrix is an n-by-n symmetric or triangular band matrix

with k superdiagonals or subdiagonals

Routine-speciﬁc error conditions are described in the respective subprogram

documentation.
