# _mm256_addsub_ps

Adds odd float32 elements and subtracts even float32 elements of vectors. The corresponding Intel® AVX instruction is VADDSUBPS.

## Syntax

extern __m256 _mm256_addsub_ps(__m256 m1, __m256 m2);

## Arguments

m1 | float32 vector used for the operation
m2 | float32 vector also used for the operation

## Description

Performs a SIMD addition of the odd single-precision floating-point elements (float32 elements) in the first source vector m1 with the odd float32 elements in the second source vector m2.

Simultaneously, the intrinsic performs subtraction of the even single-precision floating-point elements (float32 elements) in the second source vector, m2, from the even float32 elements in the first source vector, m1.

## Returns

Result of the operation stored in the result vector.
