@stdlib/math-iter-special-riemann-zeta

iterZeta

Create an iterator which evaluates the Riemann zeta function for each iterated value.

Installation

npm install @stdlib/math-iter-special-riemann-zeta

Usage

var iterZeta = require( '@stdlib/math-iter-special-riemann-zeta' );

iterZeta( iterator )

Returns an iterator which iteratively evaluates the Riemann zeta function.

var array2iterator = require( '@stdlib/array-to-iterator' );

var it = iterZeta( array2iterator( [ 1.1, -4.0 ] ) );
// returns <Object>

var v = it.next().value;
// returns ~10.584

v = it.next().value;
// returns 0.0

// ...

The returned iterator protocol-compliant object has the following properties:

• next: function which returns an iterator protocol-compliant object containing the next iterated value (if one exists) assigned to a value property and a done property having a boolean value indicating whether the iterator is finished.
• return: function which closes an iterator and returns a single (optional) argument in an iterator protocol-compliant object.

Notes

• If an iterated value is non-numeric (including NaN), the returned iterator returns NaN. If non-numeric iterated values are possible, you are advised to provide an iterator which type checks and handles non-numeric values accordingly.
• If an environment supports Symbol.iterator and a provided iterator is iterable, the returned iterator is iterable.

Examples

var uniform = require( '@stdlib/random-iter-uniform' );
var iterZeta = require( '@stdlib/math-iter-special-riemann-zeta' );

// Create a seeded iterator for generating pseudorandom numbers:
var rand = uniform( 1.1, 50.0, {
    'seed': 1234,
    'iter': 10
});

// Create an iterator which consumes the pseudorandom number iterator:
var it = iterZeta( rand );

// Perform manual iteration...
var v;
while ( true ) {
    v = it.next();
    if ( v.done ) {
        break;
    }
    console.log( v.value );
}
