    Inverse complementary error function.

    The inverse complementary error function is defined as

    Inverse complementary error function.

    where erf^{-1}(z) is the inverse error function.

    Installation

    $ npm install math-erfcinv

    Usage

    var erfcinv = require( 'math-erfcinv' );

    erfcinv( x )

    Evaluates the inverse complementary error function.

    var y = erfcinv( 0.5 );
    // returns ~0.4769
     
    = erfcinv( 0.8 );
    // returns ~0.1791
     
    = erfcinv( 0 );
    // returns +infinity
     
    = erfcinv( 2 );
    // 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 = erfcinv( -3.14 );
    // throws <Error>

    If provided NaN, the function returns NaN.

    var y = erfcinv( NaN );
    // returns NaN

    Examples

    var linspace = require( 'compute-linspace' );
    var erfcinv = require( 'math-erfcinv' );
     
    var x = linspace( 0, 2, 100 );
    var y;
    var i;
     
    for ( i = 0; i < x.length; i++ ) {
        y = erfcinv( x[ i ] );
        console.log( 'x: %d, erfcinv(x): %d', x[ i ], y );
    }

    To run the example code from the top-level application directory,

    $ node ./examples/index.js

    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,

    $ make view-browser-tests
