Hello! When I use the "_mm512_atan2_ps", I get a error: ‘_mm512_atan2_ps’ was not declared in this scope; did you mean ‘_mm512_and_ps’. And I have enabled at compile time with -mavx512f. How should I solve this problem. The CPU I'm using is: model name : 11th Gen Intel(R) Core(TM) i7-11700 @ 2.50GHz.

There is no such instruction for calculating ATAN or similar instructions.
The Intel Intrinsic Guide specify this intrinsic as a "sequence". Which means: This intrinsic generates a sequence of instructions, which may perform worse than a native instruction. Consider the performance impact of this intrinsic.
This type of intrinsic might not be supported by all compilers or supported anymore.

Thank you for reply. If I want to try to use it, can I do so by using an earlier version of the intel C/C++ compiler?
