Magnitude R←|Y

Y may be any numeric array. R is numeric composed of the absolute (unsigned) values of Y.

Note that the magnitude of a complex number $z=a+bi$ (where $a$ and $b$ are real numbers, and $i$ is the imaginary unit) is defined to be:

$\left|z\right|=\sqrt{a^2+b^2}$

Examples

2 3.4 0 2.7
