vDSP_rmsqvD

Declaration

extern void vDSP_rmsqvD(const double *__A, vDSP_Stride __IA, double *__C, vDSP_Length __N);

Parameters

• __A:

  The input vector.

• __IA:

  The distance between the elements in the input vector.

• __C:

  On output, the root mean square of the elements in the input vector.

• __N:

  The number of elements that the function processes.

Discussion

This function calculates the root mean square of the first N elements of the input vector and writes the result to the output scalar parameter, C.

The following code shows an example of using vDSP_rmsqvD:
