#3539 closed Bugs (fixed)

uBLAS: norm_inf returns incorrect output for complex vectors.

Reported by: karvind.umich@… Owned by: Gunter
Milestone: Boost 1.43.0 Component: uBLAS
Version: Boost 1.39.0 Severity: Problem
Keywords: Cc:


The attached code shows that norm_inf returns an incorrect output for vector<complex> inputs.

I've tried it with VS using boost-1.39 and boost-1.40 as well as gcc4.4 on linux and mingw/windows with boost-1.39. They all return the incorrect output for norm_inf.

(In [61136]) see #3539:

changed implementation of norm_inf and norm_1 for complex types to use abs(z) instead of max(abs(real(z)),abs(imag(z))).
