vDSP_sve
Calculates the sum of values in a single-precision vector.
Declaration
extern void vDSP_sve(const float *__A, vDSP_Stride __I, float *__C, vDSP_Length __N);Parameters
- __A:
Single-precision real input vector.
- __I:
Stride for
A. - __C:
Single-precision real output scalar.
- __N:
The number of elements to process.
Discussion
This function calculates the sum of the first N elements of A and writes the result to C:

The operation is:
C[0] = sum(A[n], 0 <= n < N);The following code shows an example of using vDSP_sve:
