beta
The beta function, also called the Euler integral, is defined as
The beta function is related to the Gamma function via the following equation
Installation
npm install @stdlib/math-base-special-beta
Usage
var beta = require( '@stdlib/math-base-special-beta' );
beta( x, y )
Evaluates the beta function.
var val = beta( 0.0, 0.5 );
// returns Infinity
val = beta( 1.0, 1.0 );
// returns 1.0
val = beta( -1.0, 2.0 );
// returns NaN
val = beta( 5.0, 0.2 );
// returns ~3.382
val = beta( 4.0, 1.0 );
// returns 0.25
Examples
var beta = require( '@stdlib/math-base-special-beta' );
var x;
var y;
for ( x = 0; x < 10; x++ ) {
for ( y = 10; y > 0; y-- ) {
console.log( 'x: %d, \t y: %d, \t f(x,y): %d', x, y, beta( x, y ) );
}
}
