Description Gael Guennebaud 2017-03-13 16:54:08 UTC
As noticed there:

https://forum.kde.org/viewtopic.php?f=74&t=139239

it should be easy to extend the current sparse-sparse products implementation to natively support operations like:

C += alpha * A * B;
C -= alpha * A * B;

without extra temporaries.
