    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 @stdlib/math-base-special-erfcinv

    Usage

    var erfcinv = require( '@stdlib/math-base-special-erfcinv' );

    erfcinv( x )

    Evaluates the inverse complementary error function.

    var y = erfcinv( 0.5 );
    // returns ~0.4769
    
    y = erfcinv( 0.8 );
    // returns ~0.1791
    
    y = erfcinv( 0.0 );
    // returns Infinity
    
    y = erfcinv( 2.0 );
    // returns -Infinity

    The domain of x is restricted to [0,2]. If x is outside this interval, the function returns NaN.

    var y = erfcinv( -3.14 );
    // returns NaN

    If provided NaN, the function returns NaN.

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

    Examples

    var linspace = require( '@stdlib/array-linspace' );
    var erfcinv = require( '@stdlib/math-base-special-erfcinv' );
    
    var x = linspace( 0.0, 2.0, 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 );
    }
