+# zlacpy
+
+> Copy all or part of a matrix `A` to another matrix `B`.
+
+
+
+## Usage
+
+```javascript
+var zlacpy = require( '@stdlib/lapack/base/zlacpy' );
+```
+
+#### zlacpy( order, uplo, M, N, A, LDA, B, LDB )
+
+Copies all or part of a matrix `A` to another matrix `B`.
+
+```javascript
+var Complex128Array = require( '@stdlib/array/complex128' );
+var reinterpret = require( '@stdlib/strided/base/reinterpret-complex128' );
+
+var A = new Complex128Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0 ] );
+var B = new Complex128Array( 4 );
+
+zlacpy( 'row-major', 'all', 2, 2, A, 2, B, 2 );
+
+var viewB = reinterpret( B, 0 );
+// returns [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0 ]
+```
+
+The function has the following parameters:
+
+- **order**: storage layout.
+- **uplo**: specifies whether to copy the upper or lower triangular/trapezoidal part of a matrix `A`.
+- **M**: number of rows in `A`.
+- **N**: number of columns in `A`.
+- **A**: input [`Complex128Array`][@stdlib/array/complex128].
+- **LDA**: stride of the first dimension of `A` (a.k.a., leading dimension of the matrix `A`).
+- **B**: output [`Complex128Array`][@stdlib/array/complex128].
+- **LDB**: stride of the first dimension of `B` (a.k.a., leading dimension of the matrix `B`).
+
+Note that indexing is relative to the first index. To introduce an offset, use [`typed array`][mdn-typed-array] views.
+
+
+
+```javascript
+var Complex128Array = require( '@stdlib/array/complex128' );
+var reinterpret = require( '@stdlib/strided/base/reinterpret-complex128' );
+
+// Initial arrays...
+var A0 = new Complex128Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0, 10.0 ] );
+var B0 = new Complex128Array( 5 );
+
+// Create offset views...
+var A1 = new Complex128Array( A0.buffer, A0.BYTES_PER_ELEMENT*1 ); // start at 2nd element
+var B1 = new Complex128Array( B0.buffer, B0.BYTES_PER_ELEMENT*1 ); // start at 2nd element
+
+zlacpy( 'row-major', 'all', 2, 2, A1, 2, B1, 2 );
+
+var viewB = reinterpret( B0, 0 );
+// returns [ 0.0, 0.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0, 10.0 ]
+```
+
+#### zlacpy.ndarray( uplo, M, N, A, sa1, sa2, oa, B, sb1, sb2, ob )
+
+Copies all or part of a matrix `A` to another matrix `B` using alternative indexing semantics.
+
+```javascript
+var Complex128Array = require( '@stdlib/array/complex128' );
+var reinterpret = require( '@stdlib/strided/base/reinterpret-complex128' );
+
+var A = new Complex128Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0 ] );
+var B = new Complex128Array( 4 );
+
+zlacpy.ndarray( 'all', 2, 2, A, 2, 1, 0, B, 2, 1, 0 );
+
+var viewB = reinterpret( B, 0 );
+// returns [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0 ]
+```
+
+The function has the following parameters:
+
+- **uplo**: specifies whether to copy the upper or lower triangular/trapezoidal part of a matrix `A`.
+- **M**: number of rows in `A`.
+- **N**: number of columns in `A`.
+- **A**: input [`Complex128Array`][@stdlib/array/complex128].
+- **sa1**: stride of the first dimension of `A`.
+- **sa2**: stride of the second dimension of `A`.
+- **oa**: starting index for `A`.
+- **B**: output [`Complex128Array`][@stdlib/array/complex128].
+- **sb1**: stride of the first dimension of `B`.
+- **sb2**: stride of the second dimension of `B`.
+- **ob**: starting index for `B`.
+
+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 Complex128Array = require( '@stdlib/array/complex128' );
+var reinterpret = require( '@stdlib/strided/base/reinterpret-complex128' );
+
+var A = new Complex128Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0, 10.0 ] );
+var B = new Complex128Array( 6 );
+
+zlacpy.ndarray( 'all', 2, 2, A, 2, 1, 1, B, 2, 1, 2 );
+
+var viewB = reinterpret( B, 0 );
+// returns [ 0.0, 0.0, 0.0, 0.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0, 10.0 ]
+```
+
+
+
+
+
+
+
+## Notes
+
+- `zlacpy()` corresponds to the [LAPACK][lapack] routine [`zlacpy`][lapack-zlacpy].
+
+
+
+
+
+
+
+## Examples
+
+
+
+```javascript
+var Complex128Array = require( '@stdlib/array/complex128' );
+var ndarray2array = require( '@stdlib/ndarray/base/to-array' );
+var uniform = require( '@stdlib/random/array/discrete-uniform' );
+var numel = require( '@stdlib/ndarray/base/numel' );
+var shape2strides = require( '@stdlib/ndarray/base/shape2strides' );
+var zlacpy = require( '@stdlib/lapack/base/zlacpy' );
+
+var shape = [ 5, 8 ];
+var order = 'row-major';
+var strides = shape2strides( shape, order );
+
+var N = numel( shape );
+
+var A = new Complex128Array( uniform( 2*N, -10, 10, {
+ 'dtype': 'generic'
+}));
+console.log( ndarray2array( A, shape, strides, 0, order ) );
+
+var B = new Complex128Array( uniform( 2*N, -10, 10, {
+ 'dtype': 'generic'
+}));
+console.log( ndarray2array( B, shape, strides, 0, order ) );

+{{alias}}( order, uplo, M, N, A, LDA, B, LDB )
+ Copies all or part of a matrix `A` to another matrix `B`.
+
+ Indexing is relative to the first index. To introduce an offset, use typed
+ array views.
+
+ Parameters
+ ----------
+ order: string
+ Row-major (C-style) or column-major (Fortran-style) order. Must be
+ either 'row-major' or 'column-major'.
+
+ uplo: string
+ Specifies whether to copy the upper or lower triangular/trapezoidal part
+ of a matrix `A`.
+
+ M: integer
+ Number of rows in `A`.
+
+ N: integer
+ Number of columns in `A`.
+
+ A: Complex128Array
+ Input matrix `A`.
+
+ LDA: integer
+ Stride of the first dimension of `A` (a.k.a., leading dimension of the
+ matrix `A`).
+
+ B: Complex128Array
+ Output matrix `B`.

+ Stride of the first dimension of `B` (a.k.a., leading dimension of the

+
+ Returns
+ -------

+ Output matrix.
+
+ Examples
+ --------
+ > var abuf = [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0 ];

+{{alias}}.ndarray( uplo, M, N, A, sa1, sa2, oa, B, sb1, sb2, ob )
+ Copies all or part of a matrix `A` to another matrix `B` using alternative
+ indexing semantics.
+
+ While typed array views mandate a view offset based on the underlying
+ buffer, the offset parameters support indexing semantics based on starting
+ indices.
+
+ Parameters
+ ----------
+ uplo: string
+ Specifies whether to copy the upper or lower triangular/trapezoidal part
+ of a matrix `A`.
+
+ M: integer

+
+ oa: integer
+ Starting index for `A`.
