itercuminabs

Create an iterator which iteratively computes a cumulative minimum absolute value.

Usage

var itercuminabs = require( '@stdlib/stats/iter/cuminabs' );

itercuminabs( iterator )

Returns an iterator which iteratively computes a cumulative minimum absolute value.

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

var arr = array2iterator( [ 2.0, 1.0, 3.0, -7.0, -5.0 ] );
var it = itercuminabs( arr );

var m = it.next().value;
// returns 2.0

m = it.next().value;
// returns 1.0

m = it.next().value;
// returns 1.0

m = it.next().value;
// returns 1.0

m = it.next().value;
// returns 1.0

Notes

  • If an iterated value is non-numeric (including NaN), the function returns NaN for all future iterations. If non-numeric iterated values are possible, you are advised to provide an iterator which type checks and handles non-numeric values accordingly.

Examples

var runif = require( '@stdlib/random/iter/uniform' );
var itercuminabs = require( '@stdlib/stats/iter/cuminabs' );

// Create an iterator for generating uniformly distributed pseudorandom numbers:
var rand = runif( -10.0, 10.0, {
    'seed': 1234,
    'iter': 100
});

// Create an iterator for iteratively computing a cumulative minimum absolute value:
var it = itercuminabs( rand );

// Perform manual iteration...
var v;
while ( true ) {
    v = it.next();
    if ( typeof v.value === 'number' ) {
        console.log( 'minabs: %d', v.value );
    }
    if ( v.done ) {
        break;
    }
}
