+# dtrmv
+
+> Perform one of the matrix-vector operations `x = A*x` or `x = A^T*x`, where `x` is an `N` element ndarray and `A` is an `N` by `N` unit, or non-unit, upper or lower triangular matrix.
+
+
+
+
+
+
+
+
+
+## Usage
+
+```javascript
+var dtrmv = require( '@stdlib/blas/base/ndarray/dtrmv' );
+```
+
+#### dtrmv( arrays )
+
+Perform one of the matrix-vector operations `x = A*x` or `x = A^T*x`, where `x` is an `N` element ndarray and `A` is an `N` by `N` unit, or non-unit, upper or lower triangular matrix.
+
+```javascript
+var Float64Vector = require( '@stdlib/ndarray/vector/float64' );
+var ndarray = require( '@stdlib/ndarray/base/ctor' );
+var Float64Array = require( '@stdlib/array/float64' );
+
+var x = new Float64Vector( [ 1.0, 2.0, 3.0 ] );
+var A = new ndarray( 'float64', new Float64Array( [ 1.0, 2.0, 3.0, 2.0, 1.0, 2.0, 3.0, 2.0, 1.0 ] ), [ 3, 3 ], [ 3, 1 ], 0, 'row-major' );
+
+var out = dtrmv( [ x, A ] );
+// x => [ 14.0, 8.0, 3.0 ]
+
+var bool = ( out === x );
+// returns true
+```
+
+The function has the following parameters:
+
+- **arrays**: array-like object containing the following ndarrays:
+
+ - a one-dimensional input ndarray.
+ - a two-dimensional input ndarray.
+
+
+
+
+
+
+
+
+
+
+
+
+
+## Examples
+
+
+
+```javascript
+var discreteUniform = require( '@stdlib/random/array/discrete-uniform' );
+var ndarray = require( '@stdlib/ndarray/base/ctor' );
+var Float64Array = require( '@stdlib/array/float64' );
+var Float64Vector = require( '@stdlib/ndarray/vector/float64' );
+var ndarray2array = require( '@stdlib/ndarray/to-array' );
+var dtrmv = require( '@stdlib/blas/base/ndarray/dtrmv' );
+
+var opts = {
+ 'dtype': 'float64'
+};
+
+var x = new Float64Vector( discreteUniform( 3, 0, 10, opts ) );
+var A = new ndarray( 'float64', new Float64Array( discreteUniform( 9, 0, 10, opts ) ), [ 3, 3 ], [ 3, 1 ], 0, 'row-major' );
+
+var out = dtrmv( [ x, A ] );
