+# dspmv
+
+> Perform the matrix-vector operation `y = α*A*x + β*y` where `α` and `β` are scalars, `x` and `y` are `N` element vectors and, `A` is an `N` by `N` symmetric matrix supplied in packed form.
+
+
+
+## Usage
+
+```javascript
+var dspmv = require( '@stdlib/blas/base/dspmv' );
+```
+
+#### dspmv( order, uplo, N, α, AP, x, sx, β, y, sy )
+
+Performs the matrix-vector operation `y = α*A*x + β*y` where `α` and `β` are scalars, `x` and `y` are `N` element vectors, and `A` is an `N` by `N` symmetric matrix supplied in packed form `AP`.
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+
+var AP = new Float64Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0 ] );
+var x = new Float64Array( [ 1.0, 1.0, 1.0 ] );
+var y = new Float64Array( [ 1.0, 1.0, 1.0 ] );
+
+dspmv( 'column-major', 'lower', 3, 1.0, AP, x, 1, 1.0, y, 1 );
+// y => [ 7.0, 12.0, 15.0 ]
+```
+
+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**: specifies the order of the matrix `A`.
+- **α**: scalar constant.
+- **AP**: packed form of a symmetric matrix `A` stored in linear memory as a [`Float64Array`][mdn-float64array].
+- **x**: input [`Float64Array`][mdn-float64array].
+- **sx**: index increment for `x`.
+- **β**: scalar constant.
+- **y**: output [`Float64Array`][mdn-float64array].
+- **sy**: index increment for `y`.
+
+The stride parameters determine how elements in the input arrays are accessed at runtime. For example, to iterate over the elements of `y` in reverse order,
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+
+var AP = new Float64Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0 ] );
+var x = new Float64Array( [ 1.0, 1.0, 1.0 ] );
+var y = new Float64Array( [ 1.0, 1.0, 1.0 ] );
+
+dspmv( 'column-major', 'lower', 3, 1.0, AP, x, 1, 1.0, y, -1 );
+// y => [ 15.0, 12.0, 7.0 ]
+```
+
+Note that indexing is relative to the first index. To introduce an offset, use [`typed array`][mdn-typed-array] views.
+
+
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+
+// Initial arrays...
+var x0 = new Float64Array( [ 1.0, 1.0 ] );
+var y0 = new Float64Array( [ 1.0, 1.0 ] );
+var AP = new Float64Array( [ 1.0, 2.0, 3.0 ] );
+
+// Create offset views...
+var x1 = new Float64Array( x0.buffer, x0.BYTES_PER_ELEMENT*0 ); // start at 1st element
+var y1 = new Float64Array( y0.buffer, y0.BYTES_PER_ELEMENT*0 ); // start at 1st element
+
+dspmv( 'row-major', 'upper', 2, 1.0, AP, x1, -1, 1.0, y1, -1 );
+// y0 => [ 6.0, 4.0 ]
+```
+
+#### dspmv.ndarray( order, uplo, N, α, AP, x, sx, ox, β, y, sy, oy )
+
+Performs the matrix-vector operation `y = α*A*x + β*y` using alternative indexing semantics and where `α` and `β` are scalars, `x` and `y` are `N` element vectors, and `A` is an `N` by `N` symmetric matrix supplied in packed form `AP`.
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+
+var AP = new Float64Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0 ] );
+var x = new Float64Array( [ 1.0, 1.0, 1.0 ] );
+var y = new Float64Array( [ 1.0, 1.0, 1.0 ] );
+
+dspmv.ndarray( 'column-major', 'lower', 3, 1.0, AP, x, 1, 0, 1.0, y, 1, 0 );
+// y => [ 7.0, 12.0, 15.0 ]
+```
+
+The function has the following additional parameters:
+
+- **ox**: starting index for `x`.
+- **oy**: 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,
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+
+var AP = new Float64Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0 ] );
+var x = new Float64Array( [ 1.0, 1.0, 1.0 ] );
+var y = new Float64Array( [ 1.0, 1.0, 1.0 ] );
+
+dspmv.ndarray( 'column-major', 'lower', 3, 1.0, AP, x, 1, 0, 1.0, y, -1, 2 );
+// y => [ 15.0, 12.0, 7.0 ]
+```
+
+
+
+
+
+
+
+## Notes
+
+- `dspmv()` corresponds to the [BLAS][blas] level 2 function [`dspmv`][dspmv].
+
+
+
+
+
+
+
+## Examples
+
+
+
+```javascript
+var discreteUniform = require( '@stdlib/random/array/discrete-uniform' );
+var dspmv = require( '@stdlib/blas/base/dspmv' );
+
+var opts = {
+ 'dtype': 'float64'
+};
+
+var N = 3;
+var AP = discreteUniform( N * ( N + 1 ) / 2, -10, 10, opts );
+
+var x = discreteUniform( N, -10, 10, opts );
+var y = discreteUniform( N, -10, 10, opts );
+
+dspmv.ndarray( 'row-major', 'upper', N, 1.0, AP, x, 1, 0, 1.0, y, 1, 0 );
+console.log( y );
