_mm256_permute2f128_pd

Permutes 128-bit double-precision floating point containing fields into a 256-bit destination vector. The corresponding Intel® AVX instruction is
VPERM2F128
.

Syntax

extern __m256d _mm256_permute2f128_pd(__m256d m1, __m256d m2, int control);
Arguments
m1
a 256-bit float64 source vector
m2
a 256-bit float64 source vector
control
an immediate byte that specifies two 2-bit control fields and two additional bits which specify zeroing behavior.
Description
Permutes 128-bit floating-point-containing fields from the first source vector
m1
and second source vector
m2
, by using bits in the 8-bit
control
argument.
Returns
A 256-bit float64 vector with permuted values.
