# Intrinsics for Set Operations

The prototypes for Intel® Advanced Vector Extensions 512 (Intel® AVX-512) intrinsics are located in the zmmintrin.h header file.
To use these intrinsics, include the immintrin.h file as follows:

    #include <immintrin.h>

variable | definition
--- | ---
src | source element to use based on writemask result
k | writemask used as a selector
a | first source vector element
