+# dgbmv
+
+> Perform one of the matrix-vector operations `y = α*A*x + β*y` or `y = α*A^T*x + β*y`.
+
+<section class="usage">
+
+## Usage
+
+```javascript
+var dgbmv = require( '@stdlib/blas/base/dgbmv' );
+```
+
+#### dgbmv( ord, trans, M, N, KL, KU, α, A, LDA, x, sx, β, y, sy )
+
+Performs one of the matrix-vector operations `y := α*A*x + β*y, or y := α*A**T*x + β*y`, where `α` and `β` are scalars, `x` and `y` are vectors and `A` is an `M` by `N` band matrix, with `KL` sub-diagonals and `KU` super-diagonals.
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+
+var A = new Float64Array( [ 0.0, 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 0.0 ] );
+var x = new Float64Array( [ 1.0, 1.0, 1.0 ] );
+var y = new Float64Array( [ 0.0, 0.0, 0.0 ] );
+
+dgbmv( 'row-major', 'no-transpose', 3, 3, 1, 1, 1.0, A, 3, x, 1, 1.0, y, 1 );
+// y => <Float64Array>[ 3.0, 12.0, 13.0 ]
+```
+
+The function has the following parameters:
+
+-   **ord**: storage layout.
+-   **trans**: specifies whether `A` should be transposed, conjugate-transposed, or not transposed.
+-   **M**: number of rows in the matrix `A`.
+-   **N**: number of columns in the matrix `A`.
+-   **α**: scalar constant.
+-   **A**: input matrix stored in linear memory as a [`Float64Array`][mdn-float32array].
+-   **lda**: stride of the first dimension of `A` (leading dimension of `A`).
+-   **x**: input [`Float64Array`][mdn-float32array].
+-   **sx**: index increment for `x`.
+-   **β**: scalar constant.
+-   **y**: output [`Float64Array`][mdn-float32array].
+-   **sy**: index increment for `y`.
+
+The stride parameters determine how operations are performed. For example, to iterate over every other element in `x` and `y`,
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+
+var A = new Float64Array( [ 0.0, 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 0.0 ] );
+var x = new Float64Array( [ 1.0, 1.0, 1.0, 1.0, 1.0 ] );
+var y = new Float64Array( [ 0.0, 0.0, 0.0, 0.0, 0.0 ] );
+
+dgbmv( 'row-major', 'no-transpose', 3, 3, 1, 1, 1.0, A, 3, x, 2, 1.0, y, 2 );
+// y => <Float64Array>[ 3.0, 0.0, 12.0, 0.0, 13.0 ]
+```
+
+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 Float64Array = require( '@stdlib/array/float64' );
+
+// Initial arrays...
+var x0 = new Float64Array( [ 1.0, 1.0, 1.0, 1.0 ] );
+var y0 = new Float64Array( [ 0.0, 0.0, 0.0, 0.0 ] );
+var A = new Float64Array( [ 0.0, 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 0.0 ] );
+
+// Create offset views...
+var x1 = new Float64Array( x0.buffer, x0.BYTES_PER_ELEMENT*1 ); // start at 2nd element
+var y1 = new Float64Array( y0.buffer, y0.BYTES_PER_ELEMENT*1 ); // start at 2nd element
+
+dgbmv( 'row-major', 'no-transpose', 3, 3, 1, 1, 1.0, A, 3, x1, 1, 1.0, y1, 1 );
+// y0 => <Float64Array>[ 0.0, 3.0, 12.0, 13.0 ]
+```
+
+<!-- lint disable maximum-heading-length -->
+#### dgbmv.ndarray( trans, M, N, KL, KU, α, A, sa1, sa2, oa, x, sx, ox, β, y, sy, oy )
+
+Performs one of the matrix-vector operations `y := α*A*x + β*y, or y := α*A**T*x + β*y`, where `α` and `β` are scalars, `x` and `y` are vectors and `A` is an `M` by `N` band matrix, with `KL` sub-diagonals and `KU` super-diagonals.
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+
+var A = new Float64Array( [ 0.0, 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 0.0 ] );
+var x = new Float64Array( [ 1.0, 1.0, 1.0 ] );
+var y = new Float64Array( [ 0.0, 0.0, 0.0 ] );
+
+dgbmv.ndarray( 'no-transpose', 3, 3, 1, 1, 1.0, A, 3, 1, 0, x, 1, 0, 1.0, y, 1, 0 );
+// y => <Float64Array>[ 3.0, 12.0, 13.0 ]
+```
+
+The function has the following additional parameters:
+
+-   **sa1**: stride of the first dimension of `A`.
+-   **sa2**: stride of the second dimension of `A`.
+-   **oa**: starting index for `A`.
+-   **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 A = new Float64Array( [ 0.0, 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 0.0 ] );
+var x = new Float64Array( [ 1.0, 1.0, 1.0 ] );
+var y = new Float64Array( [ 0.0, 0.0, 0.0 ] );
+
+dgbmv.ndarray( 'no-transpose', 3, 3, 1, 1, 1.0, A, 3, 1, 0, x, 1, 1, 1.0, y, -2, 2 );
+// y => <Float64Array>[ 12.0, 0.0, 3.0 ]
+```

+
+    Parameters
+    ----------
+    ord: string
+        Row-major (C-style) or column-major (Fortran-style) order.

+{{alias}}.ndarray( trans,M,N,KL,KU,α,A,sa1,sa2,oa,x,sx,ox,β,y,sy,oy )
+    Performs one of the matrix-vector operations `y = α*A*x + β*y` or

+    buffer, the offset parameters support indexing semantics based on starting
+    indices.
+
