+# sspr2
+
+> Perform the symmetric rank 2 operation `A := α*x*y**T + α*y*x**T + A`.
+
+
+
+## Usage
+
+```javascript
+var sspr2 = require( '@stdlib/blas/base/sspr2' );
+```
+
+#### sspr2( order, uplo, N, α, x, sx, y, sy, AP )
+
+Performs the symmetric rank 2 operation `A = α*x*y^T + α*y*x^T + A` where `α` is a scalar, `x` and `y` are `N` element vector, and `A` is an `N` by `N` symmetric matrix supplied in packed form.
+
+```javascript
+var Float32Array = require( '@stdlib/array/float32' );
+
+var AP = new Float32Array( [ 1.0, 2.0, 3.0, 1.0, 2.0, 1.0 ] );
+var x = new Float32Array( [ 1.0, 2.0, 3.0 ] );
+var y = new Float32Array( [ 1.0, 2.0, 3.0 ] );
+
+sspr2( 'row-major', 'upper', 3, 1.0, x, 1, y, 1, AP );
+// AP => [ 3.0, 6.0, 9.0, 9.0, 14.0, 19.0 ]
+```
+
+The function has the following parameters:
+
+- **order**: storage layout.
+- **uplo**: specifies whether the upper or lower triangular part of the symmetric matrix `A` is supplied.
+- **N**: number of elements along each dimension of `A`.
+- **α**: scalar constant.
+- **x**: first input [`Float32Array`][mdn-float32array].
+- **sx**: index increment for `x`.
+- **y**: second input [`Float32Array`][mdn-float32array].
+- **sy**: index increment for `y`.
+- **AP**: packed form of a symmetric matrix `A` stored as a [`Float32Array`][mdn-float32array].
+
+The stride parameters determine how elements in the input arrays are accessed at runtime. For example, to iterate over the elements of `x` and `y` in reverse order,
+
+```javascript
+var Float32Array = require( '@stdlib/array/float32' );
+
+var AP = new Float32Array( [ 1.0, 2.0, 3.0, 1.0, 2.0, 1.0 ] );
+var x = new Float32Array( [ 3.0, 2.0, 1.0 ] );
+var y = new Float32Array( [ 3.0, 2.0, 1.0 ] );
+
+sspr2( 'row-major', 'upper', 3, 1.0, x, -1, y, -1, AP );
+// AP => [ 3.0, 6.0, 9.0, 9.0, 14.0, 19.0 ]
+```
+
+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( [ 0.0, 3.0, 2.0, 1.0 ] );
+var y0 = new Float32Array( [ 0.0, 3.0, 2.0, 1.0 ] );
+var AP = new Float32Array( [ 1.0, 2.0, 3.0, 1.0, 2.0, 1.0 ] );
+
+// 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*1 ); // start at 2nd element
+
+sspr2( 'row-major', 'upper', 3, 1.0, x1, -1, y1, -1, AP );
+// AP => [ 3.0, 6.0, 9.0, 9.0, 14.0, 19.0 ]
+```
+
+#### sspr2.ndarray( uplo, N, α, x, sx, ox, y, sy, oy, AP, sap, oap )
+
+Performs the symmetric rank 2 operation `A = α*x*y^T + α*y*x^T + A`, using alternative indexing semantics and where `α` is a scalar, `x` and `y` are `N` element vector, and `A` is an `N` by `N` symmetric matrix supplied in packed form.
+
+```javascript
+var Float32Array = require( '@stdlib/array/float32' );
+
+var AP = new Float32Array( [ 1.0, 2.0, 1.0, 3.0, 2.0, 1.0 ] );
+var x = new Float32Array( [ 1.0, 2.0, 3.0 ] );
+var y = new Float32Array( [ 1.0, 2.0, 3.0 ] );
+
+sspr2.ndarray( 'column-major', 'upper', 3, 1.0, x, 1, 0, y, 1, 0, AP, 1, 0 );
+// AP => [ 3.0, 6.0, 9.0, 9.0, 14.0, 19.0 ]
+```
+
+The function has the following additional parameters:
+
+- **ox**: starting index for `x`.
+- **oy**: starting index for `y`.
+- **sap**: `AP` stride length.
+- **oap**: starting index for `AP`.
+
+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,
+
+```javascript
+var Float32Array = require( '@stdlib/array/float32' );
+
+var AP = new Float32Array( [ 1.0, 2.0, 1.0, 3.0, 2.0, 1.0 ] );
+var x = new Float32Array( [ 3.0, 2.0, 1.0 ] );
+var y = new Float32Array( [ 3.0, 2.0, 1.0 ] );
+
+sspr2.ndarray( 'column-major', 'upper', 3, 1.0, x, -1, 2, y, -1, 2, AP, 1, 0 );
+// AP => [ 3.0, 6.0, 9.0, 9.0, 14.0, 19.0 ]
+```
+
+
+
+
+
+
+
+## Notes
+
+- `sspr2()` corresponds to the [BLAS][blas] level 2 function [`sspr2`][blas-sspr2].
+
+
+
+
+
+
+
+## Examples
+
+
+
+```javascript
+var discreteUniform = require( '@stdlib/random/array/discrete-uniform' );
+var sspr2 = require( '@stdlib/blas/base/sspr2' );
+
+var opts = {
+ 'dtype': 'float32'
+};
+
+var N = 5;
+
+var AP = discreteUniform( N * ( N + 1 ) / 2, -10.0, 10.0, opts );
+var x = discreteUniform( N, -10.0, 10.0, opts );
+var y = discreteUniform( N, -10.0, 10.0, opts );
+
+sspr2( 'column-major', 'upper', N, 1.0, x, 1, y, 1, AP );
+console.log( AP );
+
+sspr2.ndarray( 'column-major', 'upper', N, 1.0, x, 1, 0, y, 1, 0, AP, 1, 0 );
