MB_DNRM2 – Euclidean norm of a vector

Block SymbolLicensing group: STANDARD
PIC

Function Description
The output reference yX is always set to the input reference uX. If HLD = on then nothing is computed otherwise the BLAS function DNRM2 is called internally:

value = DNRM2(N, uX, INCX);

where the values N and INCX are set in the following way:

The error flag E is set to on if:

See BLAS documentation [6] for more details.
