incrmin
Compute a minimum value incrementally.
Usage
var incrmin = require( '@stdlib/stats/incr/min' );
incrmin()
Returns an accumulator function
which incrementally computes a minimum value.
var accumulator = incrmin();
accumulator( [x] )
If provided an input value x
, the accumulator function returns an updated minimum value. If not provided an input value x
, the accumulator function returns the current minimum value.
var accumulator = incrmin();
var min = accumulator( 2.0 );
// returns 2.0
min = accumulator( 1.0 );
// returns 1.0
min = accumulator( 3.0 );
// returns 1.0
min = accumulator();
// returns 1.0
Notes
- Input values are not type checked. If provided
NaN
, the accumulated value isNaN
for all future invocations. If non-numeric inputs are possible, you are advised to type check and handle accordingly before passing the value to the accumulator function.
Examples
var randu = require( '@stdlib/random/base/randu' );
var incrmin = require( '@stdlib/stats/incr/min' );
var accumulator;
var v;
var i;
// Initialize an accumulator:
accumulator = incrmin();
// For each simulated datum, update the min...
for ( i = 0; i < 100; i++ ) {
v = randu() * 100.0;
accumulator( v );
}
console.log( accumulator() );
