LU Decomposition with cuDoubleComplex

Accelerated Computing GPU-Accelerated Libraries
1

Good Morning,

I would like to solve a system of equations as a set of matrices and vectors, e.g., Ax = b, using LU Decomposition for complex doubles. I have installed CUDA 11.5 on my Linux system.

Does CUDA have a library with this capability already defined in it? And if so, is there a good reference example where this is used for cuDoubleComplex types?

Thank you for any help.

Here is an example using legacy APIs (getrf and getrs) for LU factorization

Here is an example using the new Generic 64-bit APIs (Xgetrf and Xgetrs) for LU factorization

You should be able to easily modify data_type to for you needs. Let me know if you have issues.

Thank you @mnicely for information.

I think the inputs are hardcored as reals, but you should get the gist.
