### 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 ...

### How do I get rid of a "jump" in my plot?

How can I prevent plotting functions from "connecting" inside a plot points that should "wrap around" outside the plot? For example, how do I eliminate the horizontal lines running across the ...

### Getting Arg[z] to go from $0$ to $2\pi$

I'm defining branch cut functions, and I'm using $\arg(z)$ as a building block. So I just spent an hour at the whiteboard assuming that $\arg(z)$ goes from $0$ to $2\pi$, and then I implement the code,...

### Fixing phase unwrapping jumps

The problem of unwrapping 1D phase often comes up in Fourier analysis: someone computes a DFT of some data, the resulting phase values fall between $-\pi$ and $\pi$, and they'd like to "unwrap" these ...

### Finding smooth root sets to a transcendental equation

I'm trying to solve for the roots of an equation like $f(a, n) = \frac{n^2}{n+1} e^{i a n }$ for some list of complex $f$ values. For each $f$ value I know the (real) value of $a$, and I'd like ...

### Unwrapping a continuous function given by arg

I want to find the Phase difference from a function like $\arg(f(\infty))-\arg(f(0))$ considering the phase jumps in between. This function is continuous but arg might wrap it around, $[-\pi,\pi[$ is ...
