Libdaisys cmsis library is missing the arctan2 function, arm_atan2_f32, from the documented fast math functions online. Is there any way I can add this to my local daisy build environment? I’m not really familiar with how the library are built. Also I’d like to try out the square root function as well.
If not, can anyone point me to some good atan2 approximations optimised for real time dsp?
