#3056 closed Bugs (fixed)

Bug in the documentation on Webpage

Reported by: Jay Enders <pommessemmel@…> Owned by: Gunter
Milestone: Website 1.X Component: uBLAS
Version: Boost 1.38.0 Severity: Cosmetic
Keywords: Cc:

Description

There is a mixup in a table mapping uBLAS to BLAS calls on URL http://www.boost.org/doc/libs/1_39_0/libs/numeric/ublas/doc/overview.htm. In the "comment"-column the l2 has to go to the euclidean and the linf has to go to the maximum norm.

extract: _nrm2 norm_2 (x) sqrt (sum |xi|2 ) Computes the linf (euclidean) norm of a vector. i_amax norm_inf (x) index_norm_inf (x) max |xi| Computes the l2 (maximum) norm of a vector. BLAS computes the index of the first element having this value.

I closed the wrong ticket in my first commit, it should have been #3058.

Thanks for your bug reports. Please can you check that I've fixed this one correctly, it's quite a long time since I've done anything in this field. The (hopefully) corrected version is at:
