# Phase Unwrap List Of Points: Implementing continuous phase/Arg function for List of Points [duplicate]

I am looking for a function to unwrap phase of a list of points as done here for the continuous case.

I have the Re/Im data as my input and would like the unwrapped phase as the output.

Does anyone know how to do this in Mathematica?

• So when you have e.g. x^2 as real part and Cos[x] as imaginary part the something like Plot[Arg[x^2 + I Cos[x]], {x, -2 Pi, 2 Pi}]? – halirutan Sep 6 '13 at 0:33
• What did you try, and where did it fail? If you can't be more specific I have to agree that this is a duplicate of the question you referenced. – Mr.Wizard Sep 6 '13 at 5:35
