## [Help-gsl] gsl_vector stride

 From: Henry Braun Subject: [Help-gsl] gsl_vector stride Date: Mon, 7 Feb 2005 09:50:35 +0000 (GMT)

Is there any reason why the stride parameter in gsl_vector is
implemented as an (unsigned) size_t rather than as a signed
integer?

I have some convolutions $C_j = \sum_{i = 0}^n x_i y_{j-i}$
to evaluate and the obviously slick technique would be to create
views of the $y$ vector with negative stride to pass to gsl_blas_ddot.

Not to be able to do this looks like a serious gap in functionality. Is
there a workaround?
