Function

vDSP_vmaxmgD

Calculates the double-precision maximum magnitude of the corresponding values of two vectors using specified strides.

Declaration

void vDSP_vmaxmgD(const double *__A, vDSP_Stride __IA, const double *__B, vDSP_Stride __IB, double *__C, vDSP_Stride __IC, vDSP_Length __N);

Parameters

__A

Double-precision real input vector.

__IA

Stride for A.

__B

Double-precision real input vector.

__IB

Stride for B.

__C

Double-precision real output vector.

__IC

Stride for C.

__N

The number of elements to process

Discussion

This function compares the magnitudes (absolute values) of the first N elements of A with corresponding elements of B, leaving the greater (or equal) values as corresponding elements of C:

for (n = 0; n < N; ++n)
    C[n] = |B[n]| <= |A[n]| ? |A[n]| : |B[n]|;
