repeating existing elements. + +
+ +
+ + + +
+ +## Usage + +```javascript +var sleftPadCircular = require( '@stdlib/blas/ext/base/sleft-pad-circular' ); +``` + +#### sleftPadCircular( N, k, x, strideX, y, strideY ) + +Prepends elements to a single-precision floating-point strided array by circularly repeating existing elements. + +```javascript +var Float32Array = require( '@stdlib/array/float32' ); + +var x = new Float32Array( [ 1.0, 2.0, 3.0 ] ); +var y = new Float32Array( [ 0.0, 0.0, 0.0, 0.0, 0.0 ] ); + +sleftPadCircular( x.length, 2, x, 1, y, 1 ); +// y => [ 2.0, 3.0, 1.0, 2.0, 3.0 ] +``` + +The function has the following parameters: + +- **N**: number of indexed elements in `x`. +- **k**: number of elements to pad. +- **x**: input [`Float32Array`][@stdlib/array/float32]. +- **strideX**: stride length for `x`. +- **y**: output [`Float32Array`][@stdlib/array/float32]. Must contain `N + max(0,k)` indexed elements. +- **strideY**: stride length for `y`. + +The `N` and stride parameters determine which elements in the strided arrays are accessed at runtime. For example, to pad every other element in `x`: + +```javascript +var Float32Array = require( '@stdlib/array/float32' ); + +var x = new Float32Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0 ] ); +var y = new Float32Array( [ 0.0, 0.0, 0.0, 0.0, 0.0 ] ); + +sleftPadCircular( 3, 2, x, 2, y, 1 ); +// y => [ 3.0, 5.0, 1.0, 3.0, 5.0 ] +``` + +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 arrays... +var x0 = new Float32Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0 ] ); +var y0 = new Float32Array( [ 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0 ] ); + +// Create offset views... +var x1 = new Float32Array( x0.buffer, x0.BYTES_PER_ELEMENT*1 ); // start at 2nd element +var y1 = new Float32Array( y0.buffer, y0.BYTES_PER_ELEMENT*2 ); // start at 3rd element + +sleftPadCircular( 3, 2, x1, 2, y1, 1 ); +// y0 => [ 0.0, 0.0, 4.0, 6.0, 2.0, 4.0, 6.0 ] +``` + +#### sleftPadCircular.ndarray( N, k, x, strideX, offsetX, y, strideY, offsetY ) + +Prepends elements to a single-precision floating-point strided array by circularly repeating existing elements using alternative indexing semantics. + +```javascript +var Float32Array = require( '@stdlib/array/float32' ); + +var x = new Float32Array( [ 1.0, 2.0, 3.0 ] ); +var y = new Float32Array( [ 0.0, 0.0, 0.0, 0.0, 0.0 ] ); + +sleftPadCircular.ndarray( x.length, 2, x, 1, 0, y, 1, 0 ); +// y => [ 2.0, 3.0, 1.0, 2.0, 3.0 ] +``` + +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 pad every other element in the strided input array starting from the second element and to store in the last `N + k` elements of the strided output array starting from the last element: + +```javascript +var Float32Array = require( '@stdlib/array/float32' ); + +var x = new Float32Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0 ] ); +var y = new Float32Array( [ 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0 ] ); + +sleftPadCircular.ndarray( 3, 2, x, 2, 1, y, -1, y.length-1 ); +// y => [ 0.0, 0.0, 6.0, 4.0, 2.0, 6.0, 4.0 ] +``` + +
+ + + +
+ +## Notes + +- If `N <= 0`, both functions return `y` unchanged. +- If `k < 0`, both functions clamp `k` to `0`, such that indexed elements in `x` are copied to `y` without padding. + +
+ + + +
+ +## Examples + + + +```javascript +var discreteUniform = require( '@stdlib/random/array/discrete-uniform' ); +var Float32Array = require( '@stdlib/array/float32' ); +var sleftPadCircular = require( '@stdlib/blas/ext/base/sleft-pad-circular' ); + +var x = discreteUniform( 10, -100, 100, { + 'dtype': 'float32' +}); +console.log( x ); + +var k = 5; + +var y = new Float32Array( x.length + k ); +console.log( y ); + +sleftPadCircular( x.length, k, x, 1, y, 1 ); +console.log( y ); +``` + +
