phase-unwrap
============
1D phase unwrapping

## Example

```javascript
var ndarray = require("ndarray")
var unwrap = require("phase-unwrap")
var plot = require("plotter").plot


//Create a signal
var x = ndarray.zeros([100])
require("ndarray-fill")(x, function(i) {
  return (0.25 * i) % (2.0 * Math.PI)
})

//Plot input signal
plot({
  data:  Array.prototype.slice.call(x.data),
  filename: "input.svg"
})

//Unwrap
unwrap(x)

//Plot unwrapped signal
plot({
  data:  Array.prototype.slice.call(x.data),
  filename: "unwrapped.svg"
})
```

And here are the results:

### Input signal

<img src="example/input.svg">

### Unwrapped signal

<img src="example/unwrapped.svg">


## Install

    npm install phase-unwrap
    
### `require("phase-unwrap")(signal)`
Unwraps the phase angle of a signal whose values are between 0 and 2pi to a continuous signal.

* `signal` is a 1D ndarray of values

**Returns** An `signal`.  Note that the unwrapping modifies signal.

An input argument to this GitHub Action is being exported as an environment variable. If a user of this action passes untrusted input, it could be used in an insecure manner by subsequent workflow steps.

What are GitHub Actions taint flows?

GitHub Actions: Input argument exported as environment variable

An input argument to this GitHub Action is being passed back as an output. If a user of this action passes untrusted input, it could be used in an insecure manner by consuming workflows.

GitHub Actions: Input argument passed back as output

An input argument to this GitHub Action flows into a dangerous sink (such as shell command execution). This could allow a malicious user to inject commands or exploit the action.

GitHub Actions: Input argument flows to dangerous sink

A GitHub context variable (such as issue title, PR description, or comment body) is being exported as an environment variable. These context values are user-controlled and could be exploited by subsequent workflow steps.
