+
+## Usage
+
+```javascript
+var gfirstIndexEqual = require( '@stdlib/blas/ext/base/gfirst-index-equal' );
+```
+
+#### gfirstIndexEqual( N, x, strideX, y, strideY )
+
+Returns the index of the first element in a strided array equal to an element in another strided array.
+
+```javascript
+var x = [ 1.0, 2.0, 3.0, 4.0 ];
+var y = [ 0.0, 0.0, 3.0, 0.0 ];
+
+var idx = gfirstIndexEqual( x.length, x, 1, y, 1 );
+// returns 2
+```
+
+The function has the following parameters:
+
+-   **N**: number of indexed elements.
+-   **x**: first input array.
+-   **strideX**: stride length for `x`.
+-   **y**: second input array.
+-   **strideY**: stride length for `y`.
+
+If the function is unable to find matching elements, the function returns `-1`.
+
+```javascript
+var x = [ 1.0, 2.0, 3.0, 4.0 ];
+var y = [ 5.0, 6.0, 7.0, 8.0 ];
+
+var idx = gfirstIndexEqual( x.length, x, 1, y, 1 );
+// returns -1
+```
+
+The `N` and stride parameters determine which elements in the strided arrays are accessed at runtime. For example, to compare every other element:
+
+```javascript
+var x = [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0 ];
+var y = [ 0.0, 0.0, 3.0, 0.0, 0.0, 0.0 ];
+
+var idx = gfirstIndexEqual( 3, x, 2, y, 2 );
+// returns 1
+```
+
+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 arrays...
+var x0 = new Float64Array( [ 1.0, 2.0, 3.0, 4.0 ] );
+var y0 = new Float64Array( [ 0.0, 0.0, 3.0, 0.0 ] );
+
+// Create offset views...
+var x1 = new Float64Array( x0.buffer, x0.BYTES_PER_ELEMENT*1 ); // start at 2nd element
+var y1 = new Float64Array( y0.buffer, y0.BYTES_PER_ELEMENT*1 ); // start at 2nd element
+
+// Find index...
+var idx = gfirstIndexEqual( 2, x1, 1, y1, 1 );
+// returns 1
+```
+
+#### gfirstIndexEqual.ndarray( N, x, strideX, offsetX, y, strideY, offsetY )
+
+Returns the index of the first element in a strided array equal to an element in another strided array using alternative indexing semantics.
+
+```javascript
+var x = [ 1.0, 2.0, 3.0, 4.0 ];
+var y = [ 0.0, 0.0, 3.0, 0.0 ];
+
+var idx = gfirstIndexEqual.ndarray( x.length, x, 1, 0, y, 1, 0 );
+// returns 2
+```
+
+The function has the following additional parameters:
+
+-   **offsetX**: starting index for `x`.
+-   **offsetY**: starting index for `y`.
+
+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, to access only the last three elements of each strided array:
+
+```javascript
+var x = [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0 ];
+var y = [ 0.0, 0.0, 0.0, 4.0, 5.0, 6.0 ];
+
+var idx = gfirstIndexEqual.ndarray( 3, x, 1, x.length-3, y, 1, y.length-3 );
+// returns 0
+```

+
+<section class="notes">
+
+## Notes
+
+-   When comparing elements, the function checks for equality using the strict equality operator `===`. As a consequence, `NaN` values are considered distinct, and `-0` and `+0` are considered the same.
+-   Both functions support array-like objects having getter and setter accessors for array element access (e.g., [`@stdlib/array/base/accessor`][@stdlib/array/base/accessor]).
