+# saxpb
+
+> Multiply each element in a single-precision floating-point strided array by a scalar constant and add a scalar constant to each result.
+
+
+
+## Usage
+
+```javascript
+var saxpb = require( '@stdlib/blas/ext/base/saxpb' );
+```
+
+#### saxpb( N, alpha, beta, x, strideX )
+
+Multiplies each element in a single-precision floating-point strided array `x` by a scalar constant `alpha` and adds a scalar constant `beta` to each result.
+
+```javascript
+var Float32Array = require( '@stdlib/array/float32' );
+
+var x = new Float32Array( [ -2.0, 1.0, 3.0, -5.0, 4.0, 0.0, -1.0, -3.0 ] );
+
+saxpb( x.length, 5.0, 3.0, x, 1 );
+// x => [ -7.0, 8.0, 18.0, -22.0, 23.0, 3.0, -2.0, -12.0 ]
+```
+
+The function has the following parameters:
+
+- **N**: number of indexed elements.
+- **alpha**: first scalar constant.
+- **beta**: second scalar constant.
+- **x**: input [`Float32Array`][@stdlib/array/float32].
+- **strideX**: stride length.
+
+The `N` and stride parameters determine which elements in the strided array are accessed at runtime. For example, to multiply every other element by `alpha` and add `beta`:
+
+```javascript
+var Float32Array = require( '@stdlib/array/float32' );
+
+var x = new Float32Array( [ -2.0, 1.0, 3.0, -5.0, 4.0, 0.0, -1.0, -3.0 ] );
+
+saxpb( 4, 5.0, 3.0, x, 2 );
+// x => [ -7.0, 1.0, 18.0, -5.0, 23.0, 0.0, -2.0, -3.0 ]
+```
+
+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 ] );
+
+// Create an offset view...
+var x1 = new Float32Array( x0.buffer, x0.BYTES_PER_ELEMENT*1 ); // start at 2nd element
+
+// Multiply every other element by 5.0 and add 3.0...
+saxpb( 3, 5.0, 3.0, x1, 2 );
+// x0 => [ 1.0, -7.0, 3.0, -17.0, 5.0, -27.0 ]
+```
+
+#### saxpb.ndarray( N, alpha, beta, x, strideX, offsetX )
+
+Multiplies each element in a single-precision floating-point strided array `x` by a scalar constant `alpha` and adds a scalar constant `beta` to each result using alternative indexing semantics.
+
+```javascript
+var Float32Array = require( '@stdlib/array/float32' );
+
+var x = new Float32Array( [ -2.0, 1.0, 3.0, -5.0, 4.0, 0.0, -1.0, -3.0 ] );
+
+saxpb.ndarray( x.length, 5.0, 3.0, x, 1, 0 );
+// x => [ -7.0, 8.0, 18.0, -22.0, 23.0, 3.0, -2.0, -12.0 ]
+```
+
+The function has the following additional parameters:
+
+- **offsetX**: starting index.
+
+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 access only the last three elements:
+
+```javascript
+var Float32Array = require( '@stdlib/array/float32' );
+
+var x = new Float32Array( [ 1.0, -2.0, 3.0, -4.0, 5.0, -6.0 ] );
+
+saxpb.ndarray( 3, 5.0, 3.0, x, 1, x.length-3 );
+// x => [ 1.0, -2.0, 3.0, -17.0, 28.0, -27.0 ]
+```
+
+
+
+
+
+
+
+## Notes
+
+- If `N <= 0`, both functions return the strided array unchanged.
+
+
+
+
+
+
+
+## Examples
+
+
+
+```javascript
+var discreteUniform = require( '@stdlib/random/array/discrete-uniform' );
+var saxpb = require( '@stdlib/blas/ext/base/saxpb' );
+
+var x = discreteUniform( 10, -100, 100, {
+ 'dtype': 'float32'
+});
+console.log( x );
+
+saxpb( x.length, 5.0, 3.0, x, 1 );
+console.log( x );
+```
+
+
+
+
+

+
+
+
+
+
+
+### Usage
+
+```c
+#include "stdlib/blas/ext/base/saxpb.h"
+```
+
+#### stdlib_strided_saxpb( N, alpha, beta, \*X, strideX )
+
+Multiplies each element in a single-precision floating-point strided array by a scalar constant and adds a scalar constant to each result.

+
+stdlib_strided_saxpb( 4, 5.0f, 3.0f, x, 1 );
+```
+
+The function accepts the following arguments:
+
+- **N**: `[in] CBLAS_INT` number of indexed elements.
+- **alpha**: `[in] float` first scalar constant.
+- **beta**: `[in] float` second scalar constant.
+- **X**: `[inout] float*` input array.
+- **strideX**: `[in] CBLAS_INT` stride length for `X`.
+
+```c
+void stdlib_strided_saxpb( const CBLAS_INT N, const float alpha, const float beta, float *X, const CBLAS_INT strideX );
+```
+
+#### stdlib_strided_saxpb_ndarray( N, alpha, beta, \*X, strideX, offsetX )

+
+stdlib_strided_saxpb_ndarray( 4, 5.0f, 3.0f, x, 1, 0 );

+{{alias}}( N, alpha, beta, x, strideX )
+ Multiplies each element in a single-precision floating-point strided array
+ by a scalar constant and adds a scalar constant to each result.
+
+ The `N` and stride parameters determine which elements in the strided array
+ are accessed at runtime.
+
+ Indexing is relative to the first index. To introduce an offset, use typed
+ array views.
+
+ If `N <= 0`, the function returns the strided array unchanged.
+
+ Parameters
+ ----------
+ N: integer
+ Number of indexed elements.
+
+ alpha: number
+ First scalar constant.
+
+ beta: number
+ Second scalar constant.
+
+ x: Float32Array
+ Input array.
+
+ strideX: integer
+ Stride length.
+
+ Returns
+ -------
+ x: Float32Array
+ Input array.
+
+ Examples
+ --------
+ // Standard Usage:
+ > var buf = [ -2.0, 1.0, 3.0, -5.0, 4.0, 0.0, -1.0, -3.0 ];
+ > var x = new {{alias:@stdlib/array/float32}}( buf );
+ > {{alias}}( x.length, 5.0, 3.0, x, 1 )
+ [ -7.0, 8.0, 18.0, -22.0, 23.0, 3.0, -2.0, -12.0 ]
+
+ // Using `N` and stride parameters:
+ > buf = [ -2.0, 1.0, 3.0, -5.0, 4.0, 0.0, -1.0, -3.0 ];
+ > x = new {{alias:@stdlib/array/float32}}( buf );
+ > {{alias}}( 4, 5.0, 3.0, x, 2 )
+ [ -7.0, 1.0, 18.0, -5.0, 23.0, 0.0, -2.0, -3.0 ]

+ // Using view offsets:
+ > var buf0 = [ 1.0, -2.0, 3.0, -4.0, 5.0, -6.0 ];

+
+{{alias}}.ndarray( N, alpha, beta, x, strideX, offsetX )
+ Multiplies each element in a single-precision floating-point strided array
+ by a scalar constant and adds a scalar constant to each result using
+ alternative indexing semantics.
+
+ While typed array views mandate a view offset based on the underlying
+ buffer, the offset parameter supports indexing semantics based on a
+ starting index.
+
+ Parameters
+ ----------
+ N: integer
+ Number of indexed elements.
+
+ alpha: number
+ First scalar constant.
+
+ beta: number
+ Second scalar constant.
+
+ x: Float32Array
+ Input array.
+
+ strideX: integer
+ Stride length.
+
+ offsetX: integer
+ Starting index.
+
+ Returns
+ -------
+ x: Float32Array
+ Input array.
+
+ Examples
+ --------
+ // Standard Usage:
+ > var buf = [ -2.0, 1.0, 3.0, -5.0, 4.0, 0.0, -1.0, -3.0 ];
+ > var x = new {{alias:@stdlib/array/float32}}( buf );
