Detailed Description

Primitives for computing the MaximumRelative error between two signals.

Given two signals $pSrc1$ and $pSrc2$ both with length $N$ , the maximum relative error is defined as

$MaximumRelativeError = max{\frac{\left|pSrc1(n) - pSrc2(n)\right|}{max(\left|pSrc1(n)\right|, \left|pSrc2(n)\right|)}}$

If the signal is in complex format, the absolute value of the complex number is used.
