[Help-gsl] Why is Negative Stride in GSL not allowed?

[Stephan Petzchen]

Hi,

I am working on testcases for the GSL BLAS and CBLAS functionality and my
testdata also includes negative stride for vectors.

Is there a specific reason why the GSL implementation does not allow
negative stride (ATLAS also does not consider this, MKL does)?

Beside this, the BLAS spec. allows for negative stride.


Thanks in advance.

best,
