# vDSP_ztoc

Copies the contents of a split complex vector Z to an interleaved complex vector C; single precision.

## Declaration

```occ
void vDSP_ztoc(const DSPSplitComplex *__Z, vDSP_Stride __IZ, DSPComplex *__C, vDSP_Stride __IC, vDSP_Length __N);
```

## Parameters

- `__Z`: Single-precision split-complex input vector.
- `__IZ`: Stride for Z.
- `__C`: Single-precision interleaved complex output vector.
- `__IC`: Stride for C. Must be an even number.
- `__N`: The number of elements to process.

## Discussion

Discussion For best performance, C, Z.realp, and Z.imagp should be 16-byte aligned.  This performs the following operations: for (n = 0; n < N; ++n) {   C[n*IC/2].real = Z->realp[n*IZ];   C[n*IC/2].imag = Z->imagp[n*IZ]; } See also vDSP_ctoz and vDSP_ctozD.
