# Quadratic interpolation functions

Compute the quadratic interpolation between the neighboring elements in a vector.

## Topics

### Vector-to-Vector Quadratic Interpolation

[`extern void vDSP_vqint(const float *__A, const float *__B, vDSP_Stride __IB, float *__C, vDSP_Stride __IC, vDSP_Length __N, vDSP_Length __M);`](/documentation/Accelerate/vDSP_vqint)

Calculates single-precision vector quadratic interpolation.

[`extern void vDSP_vqintD(const double *__A, const double *__B, vDSP_Stride __IB, double *__C, vDSP_Stride __IC, vDSP_Length __N, vDSP_Length __M);`](/documentation/Accelerate/vDSP_vqintD)

Calculates double-precision vector quadratic interpolation.
