# vDSP_vclip

Calculates the elements of a single-precision vector clipped to the specified range using the specified stride.

## Declaration

```occ
void vDSP_vclip(const float *__A, vDSP_Stride __IA, const float *__B, const float *__C, float *__D, vDSP_Stride __ID, vDSP_Length __N);
```

## Parameters

- `__A`: Single-precision real input vector
- `__IA`: Stride for A
- `__B`: Pointer to single-precision real input scalar: low clipping threshold
- `__C`: Pointer to single-precision real input scalar: high clipping threshold
- `__D`: Single-precision real output vector
- `__ID`: Stride for D
- `__N`: The number of elements to process.

## Discussion

Discussion This performs the following operation: for (n = 0; n < N; ++n) {     if (A[n*IA] < *B)         D[n*ID] = *B;     else if (A[n*IA] > *C)         D[n*ID] = *C;     else         D[n*ID] = A[n*IA]; } Elements of A are copied to D, while clipping elements that are outside the interval [*B, *C] to the endpoints of the interval.
