MatExpr (e.g. simply scaling Mat by scalar) #1209

Thanks for the awesome effort!

I must be missing something - how do you do MatExpr stuff, e.g. Mat * 5.0 in gocv? If there's no 'operator overloading' in Go, and I don't really see functions implementing the same, how do you normally do it?

Thanks for the info!

As you already understand, overloading is not a thing that exists in the Go programming language.

Instead see functions such as https://pkg.go.dev/gocv.io/x/gocv#Mat.MultiplyFloat

Hope that helps!

Excellent! That's exactly what I have been looking for, I must have missed it! Thanks a lot for such a quick reply!
