+# sspmv
+
+> Perform one of the matrix-vector operations `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.
+
+<section class = "usage">
+
+## Usage
+
+```javascript
+var sspmv = require( '@stdlib/blas/base/sspmv' );
+```
+
+#### sspmv( ord, uplo, N, α, AP, x, sx, β, y, sy )
+
+Performs one of the matrix-vector operations `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 Float32Array = require( '@stdlib/array/float32' );
+var sspmv = require( '@stdlib/blas/base/sspmv' );
+
+var AP = new Float32Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0 ] );
+var x = new Float32Array( [ 1.0, 1.0, 1.0 ] );
+var y = new Float32Array( [ 1.0, 1.0, 1.0 ] );
+
+sspmv( 'column-major', 'lower', 3, 1.0, AP, x, 1, 1.0, y, 1 );
+// y => <Float32Array>[ 7.0, 12.0, 15.0 ]
+```
+
+The function has the following parameters:
+
+-   **ord**: storage layout.
+-   **uplo**: specifies the operation to be performed.
+-   **N**: specifies the order of the matrix `A`.
+-   **α**: scalar constant.
+-   **AP**: packed form of symmetric matrix `A` [`Float32Array`][mdn-float32array].
+-   **x**: input [`Float32Array`][mdn-float32array].
+-   **sx**: index increment for `x`.
+-   **β**: scalar constant.
+-   **y**: output [`Float32Array`][mdn-float32array].
+-   **sy**: index increment for `y`.
+
+The stride parameters determine how operations are performed. For example, to 
+perform one of the matrix-vector operations starting from the second index of `x`,
+
+```javascript
+var Float32Array = require( '@stdlib/array/float32' );
+
+var AP = new Float32Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0 ] );
+var x = new Float32Array( [ 1.0, 1.0, 1.0 ] );
+var y = new Float32Array( [ 1.0, 1.0, 1.0 ] );
+
+sspmv( 'column-major', 'lower', 3, 1.0, AP, x, 1, 1.0, y, -1 );
+// y => <Float32Array>[ 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.
+
+<!-- eslint-disable stdlib/capitalized-comments -->
+
+```javascript
+var Float32Array = require( '@stdlib/array/float32' );
+
+// Initial arrays...
+var x0 = new Float32Array( [ 1.0, 1.0 ] );
+var y0 = new Float32Array( [ 1.0, 1.0 ] );
+var AP = new Float32Array( [ 1.0, 2.0, 3.0 ] );
+
+// Create offset views...
+var x1 = new Float32Array( x0.buffer, x0.BYTES_PER_ELEMENT*0 ); // start at 1st element
+var y1 = new Float32Array( y0.buffer, y0.BYTES_PER_ELEMENT*0 ); // start at 1st element
+
+sspmv( 'row-major', 'upper', 2, 1.0, AP, x1, -1, 1.0, y1, -1 );
+// y0 => <Float32Array>[ 6.0, 4.0 ]
+```
+
+#### sspmv.ndarray( ord, uplo, N, α, AP, x, sx, ox, β, y, sy, oy )
+
+Performs one of the matrix-vector operations `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 using alternative indexing semantics.
+
+```javascript
+var Float32Array = require( '@stdlib/array/float32' );
+var sspmv = require( '@stdlib/blas/base/sspmv' );
+
+var AP = new Float32Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0 ] );
+var x = new Float32Array( [ 1.0, 1.0, 1.0 ] );
+var y = new Float32Array( [ 1.0, 1.0, 1.0 ] );
+
+sspmv.ndarray( 'column-major', 'lower', 3, 1.0, AP, x, 1, 0, 1.0, y, 1, 0 );
+// y => <Float32Array>[ 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, to perform operation with given `x` and `y` offset values`,...,
+
+```javascript
+var Float32Array = require( '@stdlib/array/float32' );
+
+var AP = new Float32Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0 ] );
+var x = new Float32Array( [ 1.0, 1.0, 1.0 ] );
+var y = new Float32Array( [ 1.0, 1.0, 1.0 ] );
+
+sspmv.ndarray( 'column-major', 'lower', 3, 1.0, AP, x, 1, 0, 1.0, y, -1, 2 );
+// y => <Float32Array>[ 15.0, 12.0, 7.0 ]
+```

+{{alias}}( ord, uplo, N, α, A, x, sx, β, y, sy )
+    Perform one of the matrix-vector operations `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.
+
+    The stride parameters determine how operations are performed.
+
+    Indexing is relative to the first index. To introduce an offset, use typed

+
+    Parameters
+    ----------
+    ord: string
+        Row-major (C-style) or column-major (Fortran-style) order.
+
+    uplo: string
+        Specifies whether `A` is upper or lower triangular matrix.

+    N: integer
+        Specifies the order of the matrix `A`.

+
+{{alias}}.ndarray( ord, uplo, N, α, A, x, sx, ox, β, y, sy, oy )
+    Perform one of the matrix-vector operations `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 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
+    ----------
+    ord: string
+        Row-major (C-style) or column-major (Fortran-style) order.
+
+    uplo: string
+        Specifies whether `A` is upper or lower triangular matrix.
+
+    N: integer
+        Specifies the order of the matrix `A`.
+
+    α: number
+        Scalar.
+
+    A: Float32Array
+        Matrix.
+
+    x: Float32Array
+        Input vector `x`.
+
+    sx: integer
+        Index increment for `x`.
+
+    ox: integer
+        Starting index for `x`.
+
+    β: number
+        Scalar.
+
+    y: Float32Array
+        Input/output vector `y`.
+
+    sy: integer
+        Index increment for `y`.
+
+    oy: integer
+        Starting index for `y`.
+
+    Returns
+    -------
+    y: Float32Array
+        Output array.
+
+    Examples
+    --------
+    // Standard usage:
+    > var x = new {{alias:@stdlib/array/float32}}( [ 1.0, 1.0 ] );
+    > var y = new {{alias:@stdlib/array/float32}}( [ 1.0, 1.0 ] );
+    > var A = new {{alias:@stdlib/array/float32}}( [ 1.0, 2.0, 3.0, 4.0 ] );
+    > var ord = 'row-major';
+    > var uplo = 'upper';
+    > {{alias}}.ndarray( ord, uplo, 2, 1.0, A, x, 1, 0, 1.0, y, 1, 0 )
+    <Float32Array>[ ~4.0, ~6.0 ]
+
+    // Advanced indexing:
+    > var x = new {{alias:@stdlib/array/float32}}( [ 1.0, 1.0 ] );
+    > var y = new {{alias:@stdlib/array/float32}}( [ 1.0, 1.0 ] );
+    > var A = new {{alias:@stdlib/array/float32}}( [ 1.0, 2.0, 3.0, 4.0 ] );
+    > var ord = 'row-major';
+    > var uplo = 'upper';
+    > {{alias}}.ndarray( ord, uplo, 2, 1.0, A, x, -1, 1, 1.0, y, -1, 1 )
