Complex number support? #435

Open cgranade opened 3 years ago

cgranade commented 3 years ago

When attempting to create a new NDArray of complex numbers, I get an exception in the Allocate method at https://github.com/SciSharp/NumSharp/blob/00d8700b00e815f321238536e0d6b4dbc9af8d6a/src/NumSharp.Core/Backends/Unmanaged/ArraySlice.cs#L387:

Are complex numbers supported as the dtype of NDArray objects, and if so, how do I allocate them? Thanks for the help, and for the awesome project!

+1. Just got to the end of a port, and realized Complex is not supported. Are there plans for this?

Any way to workaround this one? UnmanagedStorage also doesnt support Complex.
