Hi,

I am trying to implement gpu processing in my code. Most of the bessel functions are supported by gpu but besselh is not. Am I wrong? If it is not supported, is there any way around it?

I would like to calculate a hankel function of zero order 2nd type

Thanks

If "supported by GPU" means does it accepts gpuArrays as input, then yes, that appears to be the case. If instead you mean does the GPU Coder support it, then that is wrong, besselh does appear to be supported.

If the former, it appears that you can express besselh in terms of besselj and bessely

which do accept gpuArray input.
