`MulAssign<E: Entity>` #47

Closed DJDuque closed 1 year ago

DJDuque commented 1 year ago

Is your feature request related to a problem? Please describe. I have a x: Mat<f64> and an n: f64and I need to update x = n * x.

Describe the solution you'd like I think it would be convenient to implement the MulAssign trait such that we can do x *= n and it reuses the memory allocated for x.

Describe alternatives you've considered Maybe it would be good to have a generic map_with method that transforms all the elements of a matrix in place. It could be used to implement this MulAssign trait, and it would probably be useful for other things as well.
