erfcinv
The inverse complementary error function is defined as
where erf^{-1}(z)
is the inverse error function.
Installation
$ npm install math-erfcinv
Usage
var erfcinv = ;
erfcinv( x )
Evaluates the inverse complementary error function.
var y = ;// returns ~0.4769y = ;// returns ~0.1791y = ;// returns +infinityy = ;// returns -infinity
The domain of x
is restricted to [0,2]
. If x
is outside this interval, the function
will throw a RangeError
.
var y = ;// throws <Error>
If provided NaN
, the function
returns NaN
.
var y = ;// returns NaN
Examples
var linspace = ;var erfcinv = ;var x = ;var y;var i;for i = 0; i < xlength; i++y = ;console;

Tests
Unit
This repository uses tape for unit tests. To run the tests, execute the following command in the top-level application directory:
$ make test
All new feature development should have corresponding unit tests to validate correct functionality.
Test Coverage
This repository uses Istanbul as its code coverage tool. To generate a test coverage report, execute the following command in the top-level application directory:
$ make test-cov
Istanbul creates a ./reports/coverage
directory. To access an HTML version of the report,
$ make view-cov
Browser Support
This repository uses Testling for browser testing. To run the tests in a (headless) local web browser, execute the following command in the top-level application directory:
$ make test-browsers
To view the tests in a local web browser,
