+# gfindLastIndex
+
+> Return the index of the last element in a one-dimensional ndarray which passes a test implemented by a predicate function.
+
+
+
+
+
+
+
+
+
+## Usage
+
+```javascript
+var gfindLastIndex = require( '@stdlib/blas/ext/base/ndarray/gfind-last-index' );
+```
+
+#### gfindLastIndex( arrays, clbk\[, thisArg] )
+
+Returns the index of the last element in a one-dimensional ndarray which passes a test implemented by a predicate function.
+
+```javascript
+var scalar2ndarray = require( '@stdlib/ndarray/from-scalar' );
+var ndarray = require( '@stdlib/ndarray/base/ctor' );
+
+function isEven( v ) {
+ return v % 2.0 === 0.0;
+}
+
+var xbuf = [ 1.0, 3.0, 4.0, 2.0 ];
+var x = new ndarray( 'generic', xbuf, [ 4 ], [ 1 ], 0, 'row-major' );
+
+var idx = gfindLastIndex( [ x ], isEven );
+// returns 3
+```
+
+If the function is unable to find a search element, the function returns `-1`.
+
+```javascript
+var scalar2ndarray = require( '@stdlib/ndarray/from-scalar' );
+var ndarray = require( '@stdlib/ndarray/base/ctor' );
+
+function isEven( v ) {
+ return v % 2.0 === 0.0;
+}
+
+var xbuf = [ 1.0, 3.0, 5.0, 7.0 ];
+var x = new ndarray( 'generic', xbuf, [ 4 ], [ 1 ], 0, 'row-major' );
+
+var idx = gfindLastIndex( [ x ], isEven );
+// returns -1
+```
+
+The function has the following parameters:
+
+- **arrays**: array-like object containing a one-dimensional input ndarray.
+- **clbk**: callback function.
+- **thisArg**: callback execution context (_optional_).
+
+The callback function is provided the following arguments:
+
+- **value**: current array element.
+- **idx**: current array element index.
+- **array**: the input ndarray.
+
+To set the callback execution context, provide a `thisArg`.
+
+```javascript
+var ndarray = require( '@stdlib/ndarray/base/ctor' );
+
+function isEven( v ) {
+ this.count += 1;
+ return v % 2.0 === 0.0;
+}
+
+var xbuf = [ 1.0, 3.0, 4.0, 2.0 ];
+var x = new ndarray( 'generic', xbuf, [ 4 ], [ 1 ], 0, 'row-major' );
+var ctx = {
+ 'count': 0
+};
+
+var v = gfindLastIndex( [ x ], clbk, ctx );
+// returns 3
+
+var count = ctx.count;
+// returns 4
+```
+
+
+
+
+
+
+
+## Notes
+
+- If provided an empty one-dimensional ndarray, the function returns `-1`.
+- A provided callback function should return a boolean value.
+
+
+
+
+
+
+
+## Examples
+
+
+
+```javascript
+var discreteUniform = require( '@stdlib/random/array/discrete-uniform' );
+var ndarray = require( '@stdlib/ndarray/base/ctor' );
+var ndarray2array = require( '@stdlib/ndarray/to-array' );
+var gfindLastIndex = require( '@stdlib/blas/ext/base/ndarray/gfind-last-index' );
+
+function isEven( v ) {
+ return v % 2.0 === 0.0;
+}
+
+var xbuf = discreteUniform( 10, -100, 100, {
+ 'dtype': 'generic'
+});
+var x = new ndarray( 'generic', xbuf, [ xbuf.length ], [ 1 ], 0, 'row-major' );
+console.log( ndarray2array( x ) );
+
+var idx = gfindLastIndex( [ x ], isEven );
+console.log( idx );
