## Functions
void | arm_fill_f32 (float32_t value, float32_t *pDst, uint32_t blockSize)
| Fills a constant value into a floating-point vector. More...
void | arm_fill_q15 (q15_t value, q15_t *pDst, uint32_t blockSize)
| Fills a constant value into a Q15 vector. More...
void | arm_fill_q31 (q31_t value, q31_t *pDst, uint32_t blockSize)
| Fills a constant value into a Q31 vector. More...
void | arm_fill_q7 (q7_t value, q7_t *pDst, uint32_t blockSize)
| Fills a constant value into a Q7 vector. More...

## Description

Fills the destination vector with a constant value.

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

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