Syntax

d=vec_nabs(a)

Result and argument types

The following table describes the types of the returned value and the function arguments.

Result value

This function computes the absolute value of each element in the given vector and then assigns the negated value of the result to the corresponding elements in the result vector.

Formula

d[0] = -|a[0]|
d[1] = -|a[1]|
d[2] = -|a[2]|
d[3] = -|a[3]|
