+# dgetf2
+
+> Compute the LU factorization of a general $M$-by-$N$ matrix $A$ using partial pivoting with row interchanges.
+
+
+
+The `dgetf2` routine computes an LU factorization of a general $M$-by-$N$ matrix $A$ using partial pivoting with row interchanges. The factorization has the form:
+
+```math
+A = P L U
+```
+
+where $P$ is a permutation matrix, $L$ is lower unit triangular (with ones on the diagonal), and $U$ is upper triangular.
+
+
+
+
+
+
+
+## Usage
+
+```javascript
+var dgetf2 = require( '@stdlib/lapack/base/dgetf2' );
+```
+
+#### dgetf2( order, M, N, A, LDA, IPIV )
+
+Computes an `LU` factorization of a general $M$-by-$N$ matrix $A$ using partial pivoting with row interchanges.
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+var Int32Array = require( '@stdlib/array/int32' );
+
+var A = new Float64Array( [ 2.0, 1.0, 4.0, 6.0 ] );
+var IPIV = new Int32Array( 2 );
+
+var info = dgetf2( 'row-major', 2, 2, A, 2, IPIV );
+// returns 0
+```
+
+The function has the following parameters:
+
+- **order**: storage layout (`'row-major'` or `'column-major'`).
+- **M**: number of rows in matrix `A`.
+- **N**: number of columns in matrix `A`.
+- **A**: the input matrix $A$ as a [`Float64Array`][@stdlib/array/float64]. `A` is overwritten by the factors $L$ and $U$ from the factorization.
+- **LDA**: stride of the first dimension of `A` (leading dimension of the matrix `A` if column-major, or stride between rows if row-major).
+- **IPIV**: pivot indices as an [`Int32Array`][@stdlib/array/int32]. Pivot indices are 0-based. Should have at least $\min(M, N)$ elements.
+
+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' );
+var Int32Array = require( '@stdlib/array/int32' );
+
+// Initial arrays:
+var A0 = new Float64Array( [ 0.0, 2.0, 1.0, 4.0, 6.0 ] );
+var IPIV0 = new Int32Array( [ 0, 0, 0 ] );
+
+// Create offset views:
+var A1 = new Float64Array( A0.buffer, A0.BYTES_PER_ELEMENT*1 ); // start at 2nd element
+var IPIV1 = new Int32Array( IPIV0.buffer, IPIV0.BYTES_PER_ELEMENT*1 ); // start at 2nd element
+
+var info = dgetf2( 'row-major', 2, 2, A1, 2, IPIV1 );
+// returns 0
+```
+
+#### dgetf2.ndarray( M, N, A, sa1, sa2, oa, IPIV, si, oi )
+
+Computes an `LU` factorization of a general $M$-by-$N$ matrix $A$ using partial pivoting with row interchanges and alternative indexing semantics.
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+var Int32Array = require( '@stdlib/array/int32' );
+
+var A = new Float64Array( [ 2.0, 1.0, 4.0, 6.0 ] );
+var IPIV = new Int32Array( 2 );
+
+var info = dgetf2.ndarray( 2, 2, A, 2, 1, 0, IPIV, 1, 0 );
+// returns 0
+```
+
+The function has the following additional parameters:
+
+- **sa1**: row stride of `A`.
+- **sa2**: column stride of `A`.
+- **oa**: starting index of `A`.
+- **si**: stride length for `IPIV`.
+- **oi**: starting index of `IPIV`.
+
+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 Int32Array = require( '@stdlib/array/int32' );
+
+var A = new Float64Array( [ 0.0, 2.0, 1.0, 4.0, 6.0 ] );
+var IPIV = new Int32Array( 3 );
+
+var info = dgetf2.ndarray( 2, 2, A, 2, 1, 1, IPIV, 1, 1 );
+// returns 0
+```
+
+
+
+
+
+
+
+## Notes
+
+- Both functions mutate the input arrays `A` and `IPIV`.
+
+- Both functions return a status code indicating success or failure. The status code indicates the following conditions:
+
+ - `0`: factorization was successful.
+ - `>0`: $U(k, k)$ is exactly zero (where $k$ equals the status code value minus one when using zero-based indexing). The factorization has been completed, but the factor $U$ is exactly singular, and division by zero will occur if it is used to solve a system of equations.
+
+- `dgetf2()` corresponds to the [LAPACK][LAPACK] routine [`dgetf2`][lapack-dgetf2].
+
+
+
+
+
+
+
+## Examples
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+var Int32Array = require( '@stdlib/array/int32' );
+var dgetf2 = require( '@stdlib/lapack/base/dgetf2' );
+
+var A = new Float64Array( [ 2.0, 1.0, 4.0, 6.0 ] );
+var IPIV = new Int32Array( 2 );
+
+var info = dgetf2( 'row-major', 2, 2, A, 2, IPIV );
+console.log( A );
+// => [ 4.0, 6.0, 0.5, -2.0 ]
+
+console.log( IPIV );
+// => [ 1, 1 ]
+
+console.log( info );
+// => 0

+{{alias}}( order, M, N, A, LDA, IPIV )
+ Computes the LU factorization of a general M-by-N matrix A using partial
+ pivoting with row interchanges.
+
+ Indexing is relative to the first index. To introduce an offset, use typed
+ array views.
+
+ The function mutates `A` and `IPIV`.
+
+ Parameters
+ ----------
+ order: string
+ Storage layout of `A`. Must be either 'row-major' or 'column-major'.

+
+ IPIV: Int32Array
+ Vector of pivot indices. Pivot indices are 0-based. Should have at least

+
+ Returns
+ -------
+ info: integer
+ Status code. The status code indicates the following conditions:
+
+ - if equal to zero, then the factorization was successful.
+ - if greater than zero, then `U(k, k)` is exactly zero, where `k` equals

+* @param {NonNegativeInteger} N - number of columns in matrix `A`
+* @param {Float64Array} A - input matrix
+* @param {integer} strideA1 - row stride of `A`

+* @param {NonNegativeInteger} offsetA - starting index of `A`
+* @param {Int32Array} IPIV - vector of pivot indices
+* @param {integer} strideIPIV - stride length for `IPIV`
+* @param {NonNegativeInteger} offsetIPIV - starting index of `IPIV`
