In addition to functions that operate on _m256 float vectors, there are equivalent functions that operate on _m256d double vectors. float b _mm256_storeu_ps(_m256 a) : This will copy the data from the _m256 vector a into a float array b, where b will equal a, b will equal a etc._mm256_sqrt_ps(_m256 a) : This returns a _m256 vector where each of the elements are set equal to the square root of a._mm256_div_ps(_m256 a, _m256 b) : This returns a _m256 vector where each of the elements are set equal to the ratio of a and b._mm256_mul_ps(_m256 a, _m256 b) : This returns a _m256 vector where each of the elements are set equal to the product of a and b._mm256_sub_ps(_m256 a, _m256 b) : This returns a _m256 vector where each of the elements are set equal to the difference of a and b._mm256_add_ps(_m256 a, _m256 b) : This returns a _mm256 vector where each of the elements are set equal to the sum of a and b, i.e. the first element of the vector is the last variable passed to the function. _mm256_set_ps(float h, float g, float f, float e, float d, float c, float b, float a) : This returns a _m256 vector where the eight elements are set equal to the eight passed floats, i.e._mm256_set1_ps(float a) : This returns a _m256 vector, where all eight elements of the vector are set equal to a, i.e.Several functions are defined that operate on _m256 vectors, e.g. _m256d : This is a vector of four double precistion numbers (4圆4 = 256 bits)._m256 : This is a vector of eight floating point numbers (8x32 = 256 bits).The immintrin.h header file defines a set of data types that represent different types of vectors. This is needed as code compiled with AVX support with not run on processors that don’t support AVX (the program will just crash with an “unsupported” or “invalid instruction” error). You will need to pass a flag to your compiler to switch on AVX support. #ifdef _AVX_ #include #else #warning AVX is not available.
