var sminsorted = require( '@stdlib/stats-base-sminsorted' );
Computes the minimum value of a sorted single-precision floating-point strided array x
.
var Float32Array = require( '@stdlib/array-float32' );
var x = new Float32Array( [ 1.0, 2.0, 3.0 ] );
var N = x.length;
var v = sminsorted( N, x, 1 );
// returns 1.0
x = new Float32Array( [ 3.0, 2.0, 1.0 ] );
N = x.length;
v = sminsorted( N, x, 1 );
// returns 1.0
The function has the following parameters:
Float32Array
.x
.The N
and stride
parameters determine which elements in x
are accessed at runtime. For example, to compute the minimum value of every other element in x
,
var Float32Array = require( '@stdlib/array-float32' );
var floor = require( '@stdlib/math-base-special-floor' );
var x = new Float32Array( [ 1.0, 2.0, 2.0, -7.0, 3.0, 3.0, 4.0, 2.0 ] );
var N = floor( x.length / 2 );
var v = sminsorted( N, x, 2 );
// returns 1.0
Note that indexing is relative to the first index. To introduce an offset, use typed array
views.
var Float32Array = require( '@stdlib/array-float32' );
var floor = require( '@stdlib/math-base-special-floor' );
var x0 = new Float32Array( [ 2.0, 1.0, 2.0, 2.0, -2.0, 2.0, 3.0, 4.0 ] );
var x1 = new Float32Array( x0.buffer, x0.BYTES_PER_ELEMENT*1 ); // start at 2nd element
var N = floor( x0.length / 2 );
var v = sminsorted( N, x1, 2 );
// returns 1.0
Computes the minimum value of a sorted single-precision floating-point strided array using alternative indexing semantics.
var Float32Array = require( '@stdlib/array-float32' );
var x = new Float32Array( [ 1.0, 2.0, 3.0 ] );
var N = x.length;
var v = sminsorted.ndarray( N, x, 1, 0 );
// returns 1.0
The function has the following additional parameters:
x
.While typed array
views mandate a view offset based on the underlying buffer
, the offset
parameter supports indexing semantics based on a starting index. For example, to calculate the minimum value for every other value in x
starting from the second value
var Float32Array = require( '@stdlib/array-float32' );
var floor = require( '@stdlib/math-base-special-floor' );
var x = new Float32Array( [ 2.0, 1.0, 2.0, 2.0, -2.0, 2.0, 3.0, 4.0 ] );
var N = floor( x.length / 2 );
var v = sminsorted.ndarray( N, x, 2, 1 );
// returns 1.0
N <= 0
, both functions return NaN
.var Float32Array = require( '@stdlib/array-float32' );
var sminsorted = require( '@stdlib/stats-base-sminsorted' );
var x;
var i;
x = new Float32Array( 10 );
for ( i = 0; i < x.length; i++ ) {
x[ i ] = i - 5.0;
}
console.log( x );
var v = sminsorted( x.length, x, 1 );
console.log( v );
