Quite a number of applications relies on complex arithmetics. The difficulty is the lack of native support for complex_t in OpenCL, thus all operations need to be emulated. Addition and subtraction ar…

Hello,
I've been experimenting with DIRECTFN, and I was wondering if you've considered the case of complex wave numbers? I was able to modify your code so that "set_wavenumber" accepts complex argume…

**Describe the bug**
We ran pyradiomics extraction on segmentations produced by TotalSegmentator on NLST CT data. While rounding and saving general features, we found that there are complex numbers i…

I was trying to get an integer power of a complex number and I created a function:
`pN:{t:y#x;$[y=0;1a;*/t]}`
using it in this function (it generates a matrix representing a quantum Fourier tran…

## Feature Request
Hello, we use crystal in a few projects for mathematical analysis and we are quite satisfied with the performance. The only issue we face is raising a complex number to a power, fo…
