+# dlamrg
+
+> Generates a permutation list to merge the entries of two independently sorted sets into a single set sorted in ascending order.
+
+<section class="usage">
+
+## Usage
+
+```javascript
+var dlamrg = require( '@stdlib/lapack/base/dlamrg' );
+```
+
+#### dlamrg( N1, N2, A, DTRD1, DTRD2, index )
+
+Generates a permutation list to merge the entries of two independently sorted sets into a single set sorted in ascending order.
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+var Int32Array = require( '@stdlib/array/int32' );
+
+var A = new Float64Array( [ 1.0, 3.0, 2.0, 4.0, 5.0 ] );
+var index = new Int32Array( 5 );
+dlamrg( 2, 3, A, 1, 1, index );
+// index => <Int32Array>[ 0, 2, 1, 3, 4 ]
+```
+
+The function has the following parameters:
+
+-   **N1**: the length of the first sorted list to be merged.
+-   **N2**: the length of the second sorted list to be merged.
+-   **A**: the array containing the first and the second sorted lists to be merged as a [`Float64Array`][mdn-float64array].
+-   **DTRD1**: stride for the first `N1` elements in `A`.
+-   **DTRD2**: stride for the last `N2` elements in `A`.
+-   **index**: the array containing the indices of elements of `A` such that they are in ascending order.
+
+Note that indexing is relative to the first index. To introduce an offset, use [`typed array`][mdn-typed-array] views.
+
+<!-- eslint-disable stdlib/capitalized-comments -->
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+var Int32Array = require( '@stdlib/array/int32' );
+
+var A = new Float64Array( [ 1.0, 3.0, 2.0, 4.0, 5.0 ] );
+
+// Initial array:
+var index0 = new Int32Array( 6 );
+
+// Create an offset view...
+var index1 = new Int32Array( index0.buffer, index0.BYTES_PER_ELEMENT*1 ); // start at 2nd element
+
+dlamrg( 2, 3, A, 1, 1, index1 );
+// index0 => <Int32Array>[ 0, 0, 2, 1, 3, 4 ]
+```
+
+<!-- lint disable maximum-heading-length -->
+
+#### dlamrg.ndarray( N1, N2, A, strideA, offsetA, DTRD1, DTRD2, index, strideIndex, offsetIndex )
+
+Generates a permutation list to merge the entries of two independently sorted sets into a single set sorted in ascending order.
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+var Int32Array = require( '@stdlib/array/int32' );
+
+var A = new Float64Array( [ 1.0, 3.0, 2.0, 4.0, 5.0 ] );
+var index = new Int32Array( 5 );
+dlamrg.ndarray( 2, 3, A, 1, 0, 1, 1, index, 1, 0 );
+// index => <Int32Array>[ 0, 2, 1, 3, 4 ]
+```
+
+The function has the following additional parameters:
+
+-   **strideA**: stride length for `A`.
+-   **offsetA**: starting index of `A`.
+-   **strideIndex**: stride length for `index`.
+-   **offsetIndex**: starting index of `index`.
+
+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( [ 999.9, 1.0, 3.0, 2.0, 4.0, 5.0 ] );
+var index = new Int32Array( 6 );
+dlamrg.ndarray( 2, 3, A, 1, 1, 1, 1, index, 1, 1 );
+// index => <Int32Array>[ 0, 1, 3, 2, 4, 5 ]
+```

+{{alias}}( N1, N2, A, DTRD1, DTRD2, index )
+    Generates a permutation list to merge the entries of two independently
+    sorted sets into a single set sorted in ascending order.
+
+    Indexing is relative to the first index. To introduce an offset, use typed
+    array views.
+
+    Parameters
+    ----------
+    N1: number
+        The length of the first sorted list to be merged.
+
+    N2: number
+        The length of the first sorted list to be merged.
+
+    A: Float64Array
+        The array containing the first and the second sorted lists to be merged.
+
+    DTRD1: number
+        The stride for the first `N1` elements in `A`.
+
+    DTRD2: number
+        The stride for the last `N2` elements in `A`.
+
+    index: Int32Array
+        The array containing the indices of elements of `A` such that they are
+        in ascending order.
+
+    Returns
+    -------
+    out: number
+        Status code.
+
+    Examples
+    --------
+    > var A = new {{alias:@stdlib/array/float64}}( [ 1.0, 3.0, 2.0, 4.0, 5.0 ] );
+    > var index = new {{alias:@stdlib/array/int32}}( 5 );

+{{alias}}.ndarray( N1, N2, A, sA, oA, DTRD1, DTRD2, index, sIndex, oIndex )
+    Generates a permutation list to merge the entries of two independently
+    sorted sets into a single set sorted in ascending order.
+
+    While typed array views mandate a view offset based on the underlying
+    buffer, the offset parameters support indexing semantics based on starting
+    indices.
+
+    Parameters
+    ----------
+    N1: number
+        The length of the first sorted list to be merged.
+
+    N2: number
+        The length of the first sorted list to be merged.
+
+    A: Float64Array
+        The array containing the first and the second sorted lists to be merged.
+
+    sA: number
+        The stride length for `A`.
+
+    oA: number
+        The starting index of `A`.
+
+    DTRD1: number
+        The stride for the first `N1` elements in `A`.
+
+    DTRD2: number
+        The stride for the last `N2` elements in `A`.

+    sIndex: number
+        The stride length for `index`.

+        The starting index of `index`.

 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,
