Add linfNorm overload for maxNorm

[Nils Deppe]

Hi Klaus,

I hope things are going well with you. I really like the additions of the norms (I know this was quite a while back!) but was wondering if you could add an linfNorm overload for maxNorm since in a lot of physics and PDE communities it is referred to as the linfNorm and so from a user perspective it would make code easier to read. Thanks in advance!

Best regards,

Hi Nils!

That is a request that I can gladly fulfill. With the next push you will get an linfNorm() function for dense and sparse vectors and dense and sparse matrices.

Best regards,

Klaus!

Hi Klaus!

‌

Thanks for the super fast reply and this and for the great library. We really appreciate it!

Summary

The feature has been implemented, tested, optimized, and documented as required. It is immediately available via cloning the Blaze repository and will be officially released in Blaze 3.6.

linfNorm()

The linfNorm() function computes the infinity norm of the given dense or sparse vector or dense or sparse matrix:

blaze::DynamicVector<double> a;
blaze::CompressedVector<double> b;
// ... Resizing and initialization
const double linf1 = linfNorm( a );
const double linf2 = linfNorm( b );

blaze::DynamicMatrix<double> A;
blaze::CompressedMatrix<double> B;
// ... Resizing and initialization
const double linf1 = linfNorm( A );
const double linf2 = linfNorm( B );
