Returns a vector containing the results of performing a negative-absolute operation using the given vector.
This function requires the POWER7 architecture.
d=vec_nabs(a)
The following table describes the types of the returned value and the function arguments.
| d | a |
|---|---|
| vector float | vector float |
| vector double | vector double |
This function computes the absolute value of each element in the given vector and then assigns the negative value of the result to the corresponding elements in the result vector.
