_mm256_shuffle_ps

Shuffles float32 vectors. The corresponding Intel® AVX instruction is
VSHUFPS
.

Syntax

extern __m256 _mm256_shuffle_ps(__m256 m1, __m256 m2, const int select);
Arguments
m1
float32 vector used for the operation
m2
float32 vector also used for the operation
select
a constant of integer type which determines which elements of the source vectors move to the result
Description
Moves or shuffles two of the packed single-precision floating-point elements (float32 elements) from the double quadword in the source vectors to the low and high quadwords of the double quadword of the result.
The elements of the first source vector are moved to the low quadword while the elements of the second source vector are moved to the high quadword of the result. The constant defined by the
select
parameter determines which of the two elements of the source vectors are moved to the result.
Returns
Result of the shuffle operation.
