So VirtualMatrix basically generates values on-demand using that supplier function? Interesting...

Yes, it is useful in cases, when only a few of elements are non-zero. If you need fixed matrix, then you can produce it with Matrix.real() factory function. Another way is to use MatrixContext.auto().produce. It is not limited to `Double`s.

Okay, that's good to know.

I plan to add other matrix types like diagonal ones, but I need a feedback on that.
