<@U5F0TT0UX> A lot of JVM-based linear algebra libraries like ojAlgo don't have `pow()` functions. Not sure about Numpy. I don't know if it's inherently clear whether that a "dot pow" either, or just an element-wise pow() operation.

Well, in kmath the general logic is that operations are produced via context. The `MatrixContext` defines `dot` operation for any matrix so it is quite ease to extend it with power operations. It works like `context.run{ a dot b}`.
The real matrix is a special case, where context is obvious and could be inferred. That is why `dot` operation is a top level. It slightly violates the general principle, but I can't think of a case where someone will need alternative dot operation on real matrices.
