For example, to copy every other element: + +```javascript +var Float64Array = require( '@stdlib/array/float64' ); + +var x = new Float64Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0 ] ); + +dcopyWithin( 3, 0, x, 2, 1, 6 ); +// x => [ 3.0, 2.0, 5.0, 4.0, 7.0, 6.0, 7.0, 8.0 ] +``` + +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 array... +var x0 = new Float64Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0 ] ); + +// Create an offset view... +var x1 = new Float64Array( x0.buffer, x0.BYTES_PER_ELEMENT*1 ); // start at 2nd element + +// Copy within the view... +dcopyWithin( 2, 0, x1, 1, 2, 5 ); +// x0 => [ 1.0, 4.0, 5.0, 4.0, 5.0, 6.0 ] +``` + +#### dcopyWithin.ndarray( N, target, x, strideX, offsetX, start, end ) + +Performs an in-place copy of elements within a double-precision floating-point array using alternative indexing semantics. + +```javascript +var Float64Array = require( '@stdlib/array/float64' ); + +var x = new Float64Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0 ] ); + +dcopyWithin.ndarray( 2, 2, x, 1, 1, 0, 5 ); +// x => [ 1.0, 2.0, 3.0, 2.0, 3.0, 6.0 ] +``` + +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 copy elements starting from the second element: + +```javascript +var Float64Array = require( '@stdlib/array/float64' ); + +var x = new Float64Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0 ] ); + +dcopyWithin.ndarray( 2, 2, x, 1, 2, 0, 2 ); +// x => [ 1.0, 2.0, 3.0, 4.0, 3.0, 4.0 ] +``` + +
+ + + +
+ +## Notes + +- If `N <= 0`, both functions return the strided array unchanged. +- Both functions **mutate** the provided input strided array. + +
+ + + +
+ +## Examples + + + +```javascript +var discreteUniform = require( '@stdlib/random/array/discrete-uniform' ); +var dcopyWithin = require( '@stdlib/blas/ext/base/dcopy-within' ); + +var x = discreteUniform( 10, 0, 500, { + 'dtype': 'float64' +}); +console.log( x ); + +// Copy the first 3 elements to positions 5, 6, 7: +dcopyWithin( 3, 5, x, 1, 0, 3 ); +console.log( x ); + +// Copy every other element starting from the second element: +dcopyWithin( 5, 0, x, 1, 1, 9 ); +console.log( x ); +``` + +
