Function

vDSP_vneg(_:_:_:_:_:)

Calculates the negative value of each element in the supplied single-precision vector using specified stride.

Parameters

`__A`

Single-precision real input vector.

`__IA`

Address stride for `A`.

`__C`

Single-precision real output vector.

`__IC`

Address stride for `C`.

`__N`

The number of elements to process.

Discussion

This calculates the following:

Each value in `C` is replaced by the negated value of the corresponding element in `A`.
