Function

# vDSP_vthr(_:_:_:_:_:_:)

Calculates single-precision vector threshold to the specified range.

## Parameters

__A

Single-precision real input vector

__IA

Stride for A

__B

Pointer to single-precision real input scalar: lower threshold

__C

Single-precision real output vector

__IC

Stride for C

__N

The number of elements to process

## Discussion

Performs the following operation:

Creates vector C by comparing each input from vector A with scalar *B. If an input value is less than *B, *B is copied to C; otherwise, the input value from A is copied to C.
