# Extrema finding functions

Extract the values from a vector that fall outside a range.

## Topics

### Vector-to-Vector Extrema Finding

[`extern void vDSP_venvlp(const float *__A, vDSP_Stride __IA, const float *__B, vDSP_Stride __IB, const float *__C, vDSP_Stride __IC, float *__D, vDSP_Stride __ID, vDSP_Length __N);`](/documentation/Accelerate/vDSP_venvlp)

Calculates whether each element in a single-precision vector falls within a specified range.

[`extern void vDSP_venvlpD(const double *__A, vDSP_Stride __IA, const double *__B, vDSP_Stride __IB, const double *__C, vDSP_Stride __IC, double *__D, vDSP_Stride __ID, vDSP_Length __N);`](/documentation/Accelerate/vDSP_venvlpD)

Calculates whether each element in a double-precision vector falls within a specified range.
