+ +The [**range**][range] is defined as the difference between the maximum and minimum values. + +
+ + + +
+ +## Usage + +```javascript +var srangeabs = require( '@stdlib/stats/strided/srangeabs' ); +``` + +#### srangeabs( N, x, strideX ) + +Computes the [range][range] of absolute values of a single-precision floating-point strided array `x`. + +```javascript +var Float32Array = require( '@stdlib/array/float32' ); + +var x = new Float32Array( [ 1.0, -2.0, 2.0 ] ); + +var v = srangeabs( x.length, x, 1 ); +// returns 1.0 +``` + +The function has the following parameters: + +- **N**: number of indexed elements. +- **x**: input [`Float32Array`][@stdlib/array/float32]. +- **strideX**: index increment for `x`. + +The `N` and stride parameters determine which elements in the strided array are accessed at runtime. For example, to compute the [range][range] of absolute values of every other element in `x`, + +```javascript +var Float32Array = require( '@stdlib/array/float32' ); + +var x = new Float32Array( [ 1.0, 2.0, 2.0, -7.0, -2.0, 3.0, 4.0, 2.0 ] ); + +var v = srangeabs( 4, x, 2 ); +// returns 3.0 +``` + +Note that indexing is relative to the first index. To introduce an offset, use [`typed array`][mdn-typed-array] views. + + + +```javascript +var Float32Array = require( '@stdlib/array/float32' ); + +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 v = srangeabs( 4, x1, 2 ); +// returns 3.0 +``` + +#### srangeabs.ndarray( N, x, strideX, offsetX ) + +Computes the [range][range] of absolute values of a single-precision floating-point strided array using alternative indexing semantics. + +```javascript +var Float32Array = require( '@stdlib/array/float32' ); + +var x = new Float32Array( [ 1.0, -2.0, 2.0 ] ); + +var v = srangeabs.ndarray( x.length, x, 1, 0 ); +// returns 1.0 +``` + +The function has the following additional parameters: + +- **offsetX**: starting index for `x`. + +While [`typed array`][mdn-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 [range][range] of absolute values for every other element in `x` starting from the second element + +```javascript +var Float32Array = require( '@stdlib/array/float32' ); + +var x = new Float32Array( [ 2.0, 1.0, 2.0, -2.0, -2.0, 2.0, 3.0, 4.0 ] ); + +var v = srangeabs.ndarray( 4, x, 2, 1 ); +// returns 3.0 +``` + +
+ + + +
+ +## Notes + +- If `N <= 0`, both functions return `NaN`. + +
+ + + +
+ +## Examples + + + +```javascript +var discreteUniform = require( '@stdlib/random/array/discrete-uniform' ); +var srangeabs = require( '@stdlib/stats/strided/srangeabs' ); + +var x = discreteUniform( 10, -50, 50, { + 'dtype': 'float32' +}); +console.log( x ); + +var v = srangeabs( x.length, x, 1 ); +console.log( v ); +``` + +
