+# concat
+
+> Concatenate a list of ndarrays along a specified ndarray dimension.
+
+
+
+
+
+
+
+
+
+
+
+## Usage
+
+```javascript
+var concat = require( '@stdlib/ndarray/concat' );
+```
+
+#### concat( arrays, dim )
+
+Concatenates a list of ndarrays along a specified ndarray dimension.
+
+```javascript
+var ndarray = require( '@stdlib/ndarray/ctor' );
+var Float64Array = require( '@stdlib/array/float64' );
+var ndarray2array = require( '@stdlib/ndarray/to-array' );
+
+var xbuf = new Float64Array( [ -1.0, 2.0, -3.0, 4.0 ] );
+var x = new ndarray( 'float64', xbuf, [ 2, 2 ], [ 2, 1 ], 0, 'row-major' );
+
+var ybuf = new Float64Array( [ -5.0, 6.0, -7.0, 8.0, -9.0, 10.0 ] );
+var y = new ndarray( 'float64', ybuf, [ 2, 3 ], [ 3, 1 ], 0, 'row-major' );
+
+var out = concat( [ x, y ], -1 );
+// returns
+
+var arr = ndarray2array( out );
+// returns [ [ -1.0, 2.0, -5.0, 6.0, 7.0 ], [ -3.0, 4.0, 8.0, 9.0, 10.0 ] ]
+```
+
+The function accepts the following arguments:
+
+- **arrays**: a list of input ndarrays.
+- **dim**: dimension along which the arrays are concatenated. Default: `-1`.
+
+#### concat.assign( arrays, out, dim )
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+## Examples
+
+```javascript
+var discreteUniform = require( '@stdlib/random/array/discrete-uniform' );
+var ndarray = require( '@stdlib/ndarray/ctor' );
+var ndarray2array = require( '@stdlib/ndarray/to-array' );
+var concat = require( '@stdlib/ndarray/concat' );
+
+var xbuf = discreteUniform( 6, 0, 10, {
+ 'dtype': 'generic'
+});
+var x = new ndarray( 'generic', xbuf, [ 2, 3 ], [ 3, 1 ], 0, 'row-major' );
+console.log( ndarray2array( x ) );
+
+var ybuf = discreteUniform( 8, 0, 10, {
+ 'dtype': 'generic'
+});
+var y = new ndarray( 'generic', ybuf, [ 2, 4 ], [ 4, 1 ], 0, 'row-major' );
+console.log( ndarray2array( y ) );
+
+var out = concat( [ x, y ], -1 );
+console.log( ndarray2array( out ) );
