+# sgbmv
+
+> Perform one of the matrix-vector operations `y = al*A*x + b*y` or `y = al*A**T*x + b*y` with kl as sub-diagonals and ku as super-diagonals.
+
+
+
+## Usage
+
+```javascript
+var sgbmv = require( '@stdlib/blas/base/sgbmv' );
+```
+
+#### sgbmv( ord, trans, M, N, kl, ku, a, A, LDA, x, sx, b, y, sy )
+
+Performs one of the matrix-vector operations `y = a*A*x + b*y` or `y = a*A**T*x + b*y` with kl as sub-diagonals and ku as super-diagonals.
+
+```javascript
+var Float32Array = require( '@stdlib/array/float32' );
+
+var trans = 'N';
+
+var M = 4;
+var N = 3;
+var kl = 1;
+var ku = 1;
+var lda = 4;
+
+var l = 2.0;
+var b = 3.0;
+
+var A = new Float32Array( [ 0.0, 1.0, 2.0, 3.0, 5.0, 6.0, 7.0, 8.0, 10.0, 11.0, 12.0, 13.0 ] ); // eslint-disable-line max-len
+var x = new Float32Array( [ 1.0, 2.0, 3.0 ] );
+var y = new Float32Array( [ 6.0, 7.0, 8.0, 9.0, 10.0 ] );
+
+sgbmv( 'row-major', trans, M, N, kl, ku, l, A, lda, x, 1, b, y, 1 );
+// y => [ 32.0, 77.0, 110.0, 99.0, 10.0 ]
+```
+
+The function has the following parameters:
+
+- **ord**: storage layout.
+- **trans**: specifies the operation to be performed.
+- **M**: number of rows in the matrix `A`.
+- **N**: number of columns in the matrix `A`.
+- **kl**: number of sub-diagonals within the band of `A`.
+- **ku**: number of super-diagonals within the band of `A`.
+- **a**: scalar constant.
+- **A**: matrix of coefficients [`Float32Array`][mdn-float32array].
+- **lda**: stride of the first dimension of `A` (leading dimension of `A`).
+- **x**: input [`Float32Array`][mdn-float32array].
+- **sx**: index increment for `x`.
+- **b**: scalar constant.
+- **y**: output [`Float32Array`][mdn-float32array].
+- **sy**: index increment for `y`.
+
+The stride parameters determine how operations are performed. For example, to perform vector-matrix operation `y = a*A*x + b*y` or `y = a*A**T*x + b*y` with kl as sub-diagonals and ku as super-diagonals,
+
+```javascript
+var Float32Array = require( '@stdlib/array/float32' );
+
+var trans = 'N';
+
+var M = 4;
+var N = 3;
+var kl = 1;
+var ku = 1;
+var lda = 4;
+
+var a = 2.0;
+var b = 3.0;
+
+var A = new Float32Array( [ 0.0, 1.0, 2.0, 3.0, 5.0, 6.0, 7.0, 8.0, 10.0, 11.0, 12.0, 13.0 ] ); // eslint-disable-line max-len
+var x = new Float32Array( [ 1.0, 2.0, 3.0, 4.0, 5.0 ] );
+var y = new Float32Array( [ 6.0, 7.0, 8.0, 9.0, 10.0, 11.0 ] );
+
+sgbmv( 'row-major', trans, M, N, kl, ku, a, A, lda, x, 1, b, y, 1 );
+// y => [ 32.0, 77.0, 110.0, 99.0, 10.0, 11.0 ]
+```
+
+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( [ 1.0, 1.0, 1.0 ] );
+var y0 = new Float32Array( [ 1.0, 1.0 ] );
+var A = new Float32Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0 ] );
+
+// 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 4th element
+
+sgbmv( 'row-major', 'N', 2, 2, 1, 1, 1.0, A, 2, x1, -1, 1.0, y1, -1 );
+// y0 => [ 1.0, 1.0 ]
+```
+
+#### sgbmv.ndarray( ord, trans, M, N, kl, ku, a, A, LDA, x, sx, ox, b, y, sy, oy )
+
+Performs one of the matrix-vector operations `y = a*A*x + b*y` or `y = a*A**T*x + b*y` with kl as sub-diagonals and ku as super-diagonals using alternative indexing semantics.
+
+```javascript
+var Float32Array = require( '@stdlib/array/float32' );
+
+var trans = 'N';
+
+var M = 4;
+var N = 3;
+var kl = 1;
+var ku = 1;
+var lda = 4;
+
+var a = 2.0;
+var b = 3.0;
+
+var A = new Float32Array( [ 0.0, 1.0, 2.0, 3.0, 5.0, 6.0, 7.0, 8.0, 10.0, 11.0, 12.0, 13.0 ] ); // eslint-disable-line max-len
+var x = new Float32Array( [ 1.0, 2.0, 3.0 ] );
+var y = new Float32Array( [ 6.0, 7.0, 8.0, 9.0, 10.0 ] );
+
+sgbmv.ndarray( 'row-major', trans, M, N, kl, ku, a, A, lda, x, 1, 0, b, y, 1, 0 );
+// y => [ 32.0, 77.0, 110.0, 99.0, 10.0 ]
+```
+
+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 trans = 'N';
+
+var M = 4;
+var N = 3;
+var kl = 1;
+var ku = 1;
+var lda = 4;
+
+var a = 2.0;
+var b = 3.0;
+
+var A = new Float32Array( [ 0.0, 1.0, 2.0, 3.0, 5.0, 6.0, 7.0, 8.0, 10.0, 11.0, 12.0, 13.0 ] ); // eslint-disable-line max-len
+var x = new Float32Array( [ 1.0, 2.0, 3.0 ] );
+var y = new Float32Array( [ 6.0, 7.0, 8.0, 9.0, 10.0 ] );
+
+sgbmv.ndarray( 'column-major', 'N', M, N, kl, ku, a, A, 3, x, -1, 2, b, y, -1, 3 ); // eslint-disable-line max-len
+// y => [ 38.0, 61.0, 70.0, 45.0, 10.0 ]
+```
+
+
+
+
+
