The unwrap(M) function modifies phase angles in radians in the array M by adding integer multiples of 2*Pi to ensure the difference between consecutive elements in the result is less than Pi.

$\mathrm{with}\left(\mathrm{MTM}\right)\:$

$A≔⟨3.8699\,0.62832\,-1.2566\,0⟩$

$A≔\left[\begin{array}{c}3.8699\\ 0.62832\\ \mathrm{-1.2566}\\ 0\end{array}\right]$

$\mathrm{unwrap}\left(A\right)$

$\left[\begin{array}{c}3.8699\\ 6.911505308\\ 5.026585308\\ 6.283185308\end{array}\right]$

The MTM[unwrap] command was introduced in Maple 2017.
