# Complex conjugation functions

Calculate the complex conjugate of the elements in a vector.

## Topics

### Single-Vector Complex Conjugation

The functions in this group find the complex conjugate of values in a vector.

[`static func conjugate(DSPSplitComplex, count: Int, result: inout DSPSplitComplex)`](/documentation/Accelerate/vDSP/conjugate(_:count:result:)-v5m9)

Calculates the complex conjugate of the values in a single-precision vector.

[`static func conjugate(DSPDoubleSplitComplex, count: Int, result: inout DSPDoubleSplitComplex)`](/documentation/Accelerate/vDSP/conjugate(_:count:result:)-89mrk)

Calculates the complex conjugate of the values in a double-precision vector.

[`extern void vDSP_zvconj(const DSPSplitComplex *__A, vDSP_Stride __IA, const DSPSplitComplex *__C, vDSP_Stride __IC, vDSP_Length __N);`](/documentation/Accelerate/vDSP_zvconj)

Calculates the complex conjugate of the values in a single-precision vector using the specified stride.

[`extern void vDSP_zvconjD(const DSPDoubleSplitComplex *__A, vDSP_Stride __IA, const DSPDoubleSplitComplex *__C, vDSP_Stride __IC, vDSP_Length __N);`](/documentation/Accelerate/vDSP_zvconjD)

Calculates the complex conjugate of the values in a double-precision vector using the specified stride.
