+# iladlr
+
+> Return last non-zero row of matrix `A`.
+
+
+
+## Usage
+
+```javascript
+var iladlr = require( '@stdlib/lapack/base/iladlr' );
+```
+
+#### iladlr( order, M, N, A, LDA )
+
+Returns last non-zero row of matrix `A`.
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+
+var out;
+var A = new Float64Array( [ 1.0, 2.0, 3.0, 4.0 ] );
+
+out = iladlr( 'row-major', 2, 2, A, 2 );
+// returns 1
+```
+
+The function has the following parameters:
+
+- **order**: storage layout.
+- **M**: number of rows in `A`.
+- **N**: number of columns in `A`.
+- **A**: input [`Float64Array`][mdn-float64array].
+- **LDA**: stride of the first dimension of `A` (a.k.a., leading dimension of the matrix `A`).
+
+Note that indexing is relative to the first index. To introduce an offset, use [`typed array`][mdn-typed-array] views.
+
+
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+
+// Initial an array.
+var A0 = new Float64Array( [ 1.0, 2.0, 3.0, 4.0, 5.0 ] );
+
+// Create offset view.
+var A1 = new Float64Array( A0.buffer, A0.BYTES_PER_ELEMENT*1 ); // start at 2nd element
+
+var out = iladlr( 'row-major', 2, 2, A1, 2 );
+// out => 1
+```
+
+#### iladlr.ndarray( M, N, A, sa1, sa2, oa )
+
+Returns last non-zero row of matrix `A` using alternative indexing semantics.
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+
+var out;
+var A = new Float64Array( [ 1.0, 2.0, 3.0, 4.0 ] );
+
+out = iladlr.ndarray( 2, 2, A, 2, 1, 0 );
+// returns 1
+```
+
+The function has the following parameters:
+
+- **M**: number of rows in `A`.
+- **N**: number of columns in `A`.
+- **A**: input [`Float64Array`][mdn-float64array].
+- **sa1**: stride of the first dimension of `A`.
+- **sa2**: stride of the second dimension of `A`.
+- **oa**: starting index for `A`.
+
+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 out;
+var A = new Float64Array( [ 4.0, 3.0, 2.0, 4.0 ] );
+
+out = iladlr.ndarray( 2, 2, A, -2, -1, 3 );
+// returns 1
+```
+
+
+
+
+
+
+
+## Notes
+
+- `iladlr()` corresponds to the [LAPACK][lapack] routine [`iladlr`][lapack-iladlr].
+
+
+
+
+
+
+
+## Examples
+
+
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+var iladlr = require( '@stdlib/lapack/base/iladlr' );
+
+var A = new Float64Array( [ 1.0, 2.0, 3.0, 4.0 ] );
+var out = iladlr( 'row-major', 2, 2, A, 2 );
+console.log( out );
