+# sleftPadEdge
+
+> Prepend elements to a single-precision floating-point strided array by repeating the leading edge element.
+
+
+
+
+
+
+
+## Usage
+
+```javascript
+var sleftPadEdge = require( '@stdlib/blas/ext/base/sleft-pad-edge' );
+```
+
+#### sleftPadEdge( N, k, x, strideX, y, strideY )
+
+Prepends elements to a single-precision floating-point strided array by repeating the leading edge element.
+
+```javascript
+var Float32Array = require( '@stdlib/array/float32' );
+
+var x = new Float32Array( [ 1.0, 2.0, 3.0, 4.0 ] );
+var y = new Float32Array( 10 );
+
+sleftPadEdge( x.length, 6, x, 1, y, 1 );
+// y => [ 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 2.0, 3.0, 4.0 ]
+```
+
+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( 5 );
+
+sleftPadEdge( 3, 2, x, 2, y, 1 );
+// y => [ 1.0, 1.0, 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
+
+sleftPadEdge( 3, 2, x1, 2, y1, 1 );
+// y0 => [ 0.0, 0.0, 2.0, 2.0, 2.0, 4.0, 6.0 ]
+```
+
+#### sleftPadEdge.ndarray( N, k, x, strideX, offsetX, y, strideY, offsetY )
+
+Prepends elements to a single-precision floating-point strided array by repeating the leading edge element using alternative indexing semantics.
+
+```javascript
+var Float32Array = require( '@stdlib/array/float32' );
+
+var x = new Float32Array( [ 1.0, 2.0, 3.0, 4.0 ] );
+var y = new Float32Array( 10 );
+
+sleftPadEdge.ndarray( x.length, 6, x, 1, 0, y, 1, 0 );
+// y => [ 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 2.0, 3.0, 4.0 ]
+```
+
+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 ] );
+
+sleftPadEdge.ndarray( 3, 2, x, 2, 1, y, -1, y.length-1 );
+// y => [ 0.0, 0.0, 6.0, 4.0, 2.0, 2.0, 2.0 ]
+```
+
+
+
+
+
+
+
+## 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 sleftPadEdge = require( '@stdlib/blas/ext/base/sleft-pad-edge' );
+
+var x = discreteUniform( 5, -100, 100, {
+ 'dtype': 'float32'
+});
+console.log( x );
+
+var k = 5;
+
+var y = new Float32Array( x.length + k );
+console.log( y );
+
+sleftPadEdge( x.length, k, x, 1, y, 1 );
+console.log( y );
+```

+{{alias}}( N, k, x, strideX, y, strideY )
+ Prepends elements to a single-precision floating-point strided array by
+ repeating the leading edge element.
+
+ The `N` and stride parameters determine which elements in the strided
+ arrays are accessed at runtime.
+
+ Indexing is relative to the first index. To introduce an offset, use a
+ typed array view.
+
+ If `N <= 0`, the function returns `y` unchanged.
+
+ If `k < 0`, the function clamps `k` to `0`, such that indexed elements
+ in `x` are copied to `y` without padding.
+
+ Parameters
+ ----------
+ N: integer
+ Number of indexed elements in `x`.
+
+ k: integer
+ Number of elements to pad.
+
+ x: Float32Array
+ Input array.
+
+ strideX: integer
+ Stride length for `x`.
+
+ y: Float32Array
+ Output array. Must contain `N + max(0,k)` indexed elements.
+
+ strideY: integer
+ Stride length for `y`.
+
+ Returns
+ -------
+ y: Float32Array
+ Output array.
+
+ Examples
+ --------
+ // Standard Usage:
+ > var x = new {{alias:@stdlib/array/float32}}( [ 1.0, 2.0, 3.0, 4.0 ] );
+ > var y = new {{alias:@stdlib/array/float32}}( 10 );
+ > {{alias}}( x.length, 6, x, 1, y, 1 )
+ [ 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 2.0, 3.0, 4.0 ]
+
+ // Using `N` and stride parameters:
+ > x = new {{alias:@stdlib/array/float32}}( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0 ] );
+ > y = new {{alias:@stdlib/array/float32}}( 5 );
+ > {{alias}}( 3, 2, x, 2, y, 1 )
+ [ 1.0, 1.0, 1.0, 3.0, 5.0 ]
+
+ // Using view offsets:
+ > var x0 = new {{alias:@stdlib/array/float32}}( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0 ] );
+ > var y0 = new {{alias:@stdlib/array/float32}}( [ 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0 ] );

+
+{{alias}}.ndarray( N, k, x, strideX, offsetX, y, strideY, offsetY )
+ Prepends elements to a single-precision floating-point strided array by
+ repeating the leading edge element using alternative indexing semantics.
+
+ While typed array views mandate a view offset based on the underlying
+ buffer, the offset parameters support indexing semantics based on
+ starting indices.
+
+ Parameters
+ ----------
+ N: integer
+ Number of indexed elements in `x`.
+
+ k: integer
+ Number of elements to pad.
+
+ x: Float32Array
+ Input array.
+
+ strideX: integer
+ Stride length for `x`.
+
+ offsetX: integer
+ Starting index for `x`.
+
+ y: Float32Array
+ Output array. Must contain `N + max(0,k)` indexed elements.
+
+ strideY: integer
+ Stride length for `y`.
+
+ offsetY: integer
+ Starting index for `y`.
+
+ Returns
+ -------
+ y: Float32Array
+ Output array.
+
+ Examples
+ --------
+ // Standard Usage:
+ > var x = new {{alias:@stdlib/array/float32}}( [ 1.0, 2.0, 3.0, 4.0 ] );
