arrays. + +
+ +The [minkowski distance][wikipedia-minkowski-distance] is defined as + + + +```math +D(A,B) = \left( \sum_{i=0}^{N-1} \left| a_i - b_i \right|^p \right)^{\frac{1}{p}} +``` + + + +where `a_i` and `b_i` are the _ith_ components of vectors **A** and **B**, respectively. + +
+ + + +
+ +## Usage + +```javascript +var dminkowski = require( '@stdlib/stats/strided/distances/dminkowski' ); +``` + +#### dminkowski( N, P, x, strideX, y, strideY ) + +Computes the Minkowski distance between two double-precision floating-point strided arrays. + +```javascript +var Float64Array = require( '@stdlib/array/float64' ); + +var x = new Float64Array( [ 4.0, 2.0, -3.0, 5.0, -1.0 ] ); +var y = new Float64Array( [ 2.0, 6.0, -1.0, -4.0, 8.0 ] ); + +var z = dminkowski( x.length, 3, x, 1, y, 1 ); +// returns ~11.543 +``` + +The function has the following parameters: + +- **N**: number of indexed elements. +- **P**: order of the Minkowski norm. +- **x**: input [`Float64Array`][@stdlib/array/float64]. +- **strideX**: stride length of `x`. +- **y**: input [`Float64Array`][@stdlib/array/float64]. +- **strideY**: stride length of `y`. + +The `N` and stride parameters determine which elements in the strided arrays are accessed at runtime. For example, to calculate the Minkowski distance between every other element in `x` and the first `N` elements of `y` in reverse order, + +```javascript +var Float64Array = require( '@stdlib/array/float64' ); + +var x = new Float64Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0 ] ); +var y = new Float64Array( [ 1.0, 1.0, 1.0, 1.0, 1.0, 1.0 ] ); + +var z = dminkowski( 3, 3, x, 2, y, -1 ); +// returns ~4.16 +``` + +Note that indexing is relative to the first index. To introduce an offset, use [`typed array`][mdn-typed-array] views. + + + +```javascript +var Float64Array = require( '@stdlib/array/float64' ); + +// Initial arrays... +var x0 = new Float64Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0 ] ); +var y0 = new Float64Array( [ 7.0, 8.0, 9.0, 10.0, 11.0, 12.0 ] ); + +// Create offset views... +var x1 = new Float64Array( x0.buffer, x0.BYTES_PER_ELEMENT*1 ); // start at 2nd element +var y1 = new Float64Array( y0.buffer, y0.BYTES_PER_ELEMENT*3 ); // start at 4th element + +var z = dminkowski( 3, 3, x1, 1, y1, 1 ); +// returns ~11.538 +``` + +#### dminkowski.ndarray( N, P, x, strideX, offsetX, y, strideY, offsetY ) + +Computes the Minkowski distance between two double-precision floating-point strided arrays using alternative indexing semantics. + +```javascript +var Float64Array = require( '@stdlib/array/float64' ); + +var x = new Float64Array( [ 4.0, 2.0, -3.0, 5.0, -1.0 ] ); +var y = new Float64Array( [ 2.0, 6.0, -1.0, -4.0, 8.0 ] ); + +var z = dminkowski.ndarray( x.length, 3, x, 1, 0, y, 1, 0 ); +// returns ~11.543 +``` + +The function has the following additional parameters: + +- **offsetX**: starting index for `x`. +- **offsetY**: starting index for `y`. + +While [`typed array`][mdn-typed-array] views mandate a view offset based on the underlying buffer, the offset parameters support indexing semantics based on starting indices. For example, to calculate the Minkowski distance between every other element in `x` starting from the second element with the last 3 elements in `y` in reverse order + +```javascript +var Float64Array = require( '@stdlib/array/float64' ); + +var x = new Float64Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0 ] ); +var y = new Float64Array( [ 7.0, 8.0, 9.0, 10.0, 11.0, 12.0 ] ); + +var z = dminkowski.ndarray( 3, 3, x, 2, 1, y, -1, y.length-1 ); +// returns ~11.206 +``` + +
+ + + +
+ +## Notes + +- If `N <= 0`, both functions return `NaN`. + +
+ + + +
+ +## Examples + + + +```javascript +var discreteUniform = require( '@stdlib/random/array/discrete-uniform' ); +var dminkowski = require( '@stdlib/stats/strided/distances/dminkowski' ); + +var opts = { + 'dtype': 'float64' +}; +var x = discreteUniform( 10, 0, 100, opts ); +console.log( x ); + +var y = discreteUniform( x.length, 0, 10, opts ); +console.log( y ); + +var out = dminkowski.ndarray( x.length, 3, x, 1, 0, y, -1, y.length-1 ); +console.log( out ); +``` + +
