Description

Returns the absolute values of each element. Note that the absolute value of a complex number is of type double. Therefore, if abs() is invoked for class RWMathVec<DComplex>, a vector of class RWMathVec<double> is returned.

Example Program

#include <rw/math/mathvec.h>
#include <rw/rstream.h>
const double adata[] = {1.2,2.4,-1.2,0.8,-4.5};
int main() {
        RWMathVec<double> a(adata,5);
        RWMathVec<double> b = abs(a);
        cout << b;
}

Program Output:

[ 1.2  2.4  1.2  0.8  4.5 ]
