+## Usage
+
+```javascript
+var filled2dBy = require( '@stdlib/array/base/symmetric-banded/filled2d-by' );
+```
+
+#### filled2dBy( N, k, fill, clbk\[, thisArg] )
+
+Returns a filled two-dimensional symmetric banded nested array according to a provided callback function.
+
+```javascript
+function clbk( idx ) {
+    return idx[ 0 ] + idx[ 1 ];
+}
+
+var out = filled2dBy( 3, 1, 0, clbk );
+// returns [ [ 0, 1, 0 ], [ 1, 2, 3 ], [ 0, 3, 4 ] ]
+```
+
+The function accepts the following arguments:
+
+-   **N**: number of rows and columns.
+-   **k**: number of super-/sub-diagonals.
+-   **fill**: fill value for elements outside the band.
+-   **clbk**: callback function.
+-   **thisArg**: callback function execution context (_optional_).
+
+When invoked, a callback function is provided a single argument:
+
+-   **indices**: current array element indices.
+
+To set the callback execution context, provide a `thisArg`.
+
+<!-- eslint-disable no-invalid-this -->
+
+```javascript
+function clbk() {
+    this.count += 1;
+    return 1;
+}
+
+var ctx = {
+    'count': 0
+};
+
+var out = filled2dBy( 2, 1, 0, clbk, ctx );
+// returns [ [ 1, 1 ], [ 1, 1 ] ];
+
+var cnt = ctx.count;
+// returns 3

+## Notes

+-   As the output array is symmetric and banded, the callback function is only invoked for the elements residing within the band in the upper triangle of the output array.
