## Syntax

extern void _mm256_storeu_pd(double *a, __m256d b);

## Arguments

*a | pointer to a memory location that can hold double-precision floating point (float64) values
b | float64 vector

## Description

Performs a store operation by moving packed double-precision floating point values (float64 values) from a float64 vector, b, to a 256-bit unaligned memory location, pointed to by a.
