[vox-tech] [OT] Numerical algorithms in C

[Bill Broadley]

You didn't mention your CPU, but AMD has a AMD core math library, and
intel has a math kernel library.  Both available for linux, they might
have some of the routines you need.  The ones you do find are likely
to be well optimized for the CPUs they are targeted at.
