For example, to copy every other element: + +```javascript +var Float32Array = require( '@stdlib/array/float32' ); + +var x = new Float32Array( [ 1.0, 0.0, 3.0, 0.0, 5.0, 0.0, 7.0, 0.0 ] ); + +scopyWithin( 3, 0, 1, 6, x, 2 ); +// x => [ 3.0, 0.0, 5.0, 0.0, 7.0, 0.0, 7.0, 0.0 ] +``` + +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' ); + +// Initial array... +var x0 = new Float32Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0 ] ); + +// Create an offset view... +var x1 = new Float32Array( x0.buffer, x0.BYTES_PER_ELEMENT*1 ); // start at 2nd element + +// Copy within the view... +scopyWithin( 3, 0, 2, 5, x1, 1 ); +// x0 => [ 1.0, 4.0, 5.0, 6.0, 5.0, 6.0, 7.0, 8.0 ] +``` + +#### scopyWithin.ndarray( N, target, start, end, x, strideX, offsetX ) + +Performs an in-place copy of elements within a single-precision floating-point array using alternative indexing semantics. + +```javascript +var Float32Array = require( '@stdlib/array/float32' ); + +var x = new Float32Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0 ] ); + +scopyWithin.ndarray( x.length, 3, 1, 4, x, 1, 0 ); +// x => [ 1.0, 2.0, 3.0, 2.0, 3.0, 4.0 ] +``` + +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 Float32Array = require( '@stdlib/array/float32' ); + +var x = new Float32Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0 ] ); + +scopyWithin.ndarray( 3, 2, 0, 3, x, 1, 2 ); +// x => [ 1.0, 2.0, 3.0, 4.0, 3.0, 4.0, 5.0, 8.0 ] +``` + +
+ + + +
+ +## Notes + +- If `N <= 0`, both functions return the strided array unchanged. +- If `target >= N`, both functions return the strided array unchanged. +- Both functions **mutate** the provided input strided array. + +
