+# mskfilter-map
+
+> Apply a mask to a provided input array and return a new array after applying a mapping function.
+
+<section class="usage">
+
+## Usage
+
+```javascript
+var mskfilterMap = require( '@stdlib/array/base/mskfilter-map' );
+```
+
+#### mskfilterMap( x, mask, clbk\[, thisArg] )
+
+Returns a new array by applying a mask to a provided input array after applying mapping function.
+
+```javascript
+var x = [ 1, 2, 3, 4 ];
+
+function customMapping( value ) {
+    return value * 2;
+}
+
+var y = mskfilterMap( x, [ 0, 1, 0, 1 ], customMapping );
+// returns [ 4, 8 ]
+```
+
+The function supports the following parameters:
+
+-   **x**: input array.
+-   **mask**: mask array.
+-   **clbk**: function to apply.
+-   **thisArg**: applied function execution context (_optional_).
+
+To set the applied function's execution context, provide a `thisArg`.
+
+The function **always** returns a new "generic" array.
+
+#### mskfilterMap.assign( x, mask, out, stride, offset )
+
+Applies a mask & mapping function to a provided input array and assigns unmasked values to elements in a provided output array.
+
+```javascript
+var x = [ 1, 2, 3, 4 ];
+var mask = [ 0, 1, 0, 1 ];
+
+var out = [ 0, 0, 0, 0 ];
+
+function clbk( val ) {
+    return val * 2;
+}
+
+var arr = mskfilterMap.assign( x, mask, out, -2, out.length-1, clbk );
+// returns [ 0, 8, 0, 4 ]
+
+var bool = ( arr === out );
+// returns true
+```
+
+The function supports the following parameters:
+
+-   **x**: input array.
+-   **mask**: mask array.
+-   **out**: output array.
+-   **stride**: output array stride.
+-   **offset**: output array offset.
+-   **clbk**: function to apply.
+-   **thisArg**: applied function execution context (_optional_).
+
+</section>
+
+<!-- /.usage -->
+
+<section class="notes">
+
+## Notes
+
+-   If a `mask` array element is truthy, the corresponding element in `x` is **included** in the output array; otherwise, the corresponding element in `x` is "masked" and thus **excluded** from the output array.
+
+</section>
+
+<!-- /.notes -->
+
+<section class="examples">
+
+## Examples
+
+<!-- eslint no-undef: "error" -->
+
+```javascript
+var zeroTo = require( '@stdlib/array/base/zero-to' );
+var bernoulli = require( '@stdlib/random/array/bernoulli' );
+var mskfilterMap = require( '@stdlib/array/base/mskfilter-map' );
+
+// Generate a linearly spaced array:
+var x = zeroTo( 20 );
+console.log( x );
+
+// Generate a random mask:
+var mask = bernoulli( x.length, 0.5, {
+    'dtype': 'generic'
+});
+console.log( mask );
+
+// Mapping functions
+function square( val ) {
+    return val * val;
+}
+
+// Filter an array using the mask:
+var y = mskfilterMap( x, mask, square );
+console.log( y );
