## Functions

void | arm_copy_f32 (float32_t *pSrc, float32_t *pDst, uint32_t blockSize)
| Copies the elements of a floating-point vector.
void | arm_copy_q15 (q15_t *pSrc, q15_t *pDst, uint32_t blockSize)
| Copies the elements of a Q15 vector.
void | arm_copy_q31 (q31_t *pSrc, q31_t *pDst, uint32_t blockSize)
| Copies the elements of a Q31 vector.
void | arm_copy_q7 (q7_t *pSrc, q7_t *pDst, uint32_t blockSize)
| Copies the elements of a Q7 vector.

## Description

Copies sample by sample from source vector to destination vector.

            pDst[n] = pSrc[n];   0 <= n < blockSize.

There are separate functions for floating point, Q31, Q15, and Q7 data types.
