void | arm_rms_f16 (const float16_t *pSrc, uint32_t blockSize, float16_t *pResult) |
Root Mean Square of the elements of a floating-point vector. | |
void | arm_rms_f32 (const float32_t *pSrc, uint32_t blockSize, float32_t *pResult) |
Root Mean Square of the elements of a floating-point vector. | |
void | arm_rms_q15 (const q15_t *pSrc, uint32_t blockSize, q15_t *pResult) |
Root Mean Square of the elements of a Q15 vector. | |
void | arm_rms_q31 (const q31_t *pSrc, uint32_t blockSize, q31_t *pResult) |
Root Mean Square of the elements of a Q31 vector. | |
Calculates the Root Mean Square of the elements in the input vector. The underlying algorithm is used:
Result = sqrt(((pSrc[0] * pSrc[0] + pSrc[1] * pSrc[1] + ... + pSrc[blockSize-1] * pSrc[blockSize-1]) / blockSize));
There are separate functions for floating point, Q31, and Q15 data types.
