Evaluate the modified Helmholtz potential sum (single precision version).

Arguments

• source_ptr - Pointer to a (3, nsources) array of sources.
• target_ptr - Pointer to a (3, ntargets) array of targets.
• charge_ptr - Pointer to a (ncharge_vecs, nsources) array of ncharge_vecs charge vectors.
• result_ptr - Pointer to an existing (ncharge_vecs, ntargets, 1) array (if return_gradients is false) or to an (ncharge_vecs, ntargets, 4) array (if `return_gradients is true) that stores the result.
• omega - The omega parameter of the kernel.
• nsources - Number of sources.
• ntargets - Number of targets.
• ncharge_vecs - Number of charge vectors.
• return_gradients - If true return also the gradients.
• num_threads - Number of threads to use
