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 $z = a + b i$ (where $a$ and $b$ are real numbers, and $i$ is the imaginary unit) is defined to be:

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

Examples

2 3.4 0 2.7
