+# mskbinary3d
+
+> Apply a binary callback to elements in two three-dimensional nested input arrays according to elements in a three-dimensional nested mask array and assign results to elements in a three-dimensional nested output array.
+
+
+
+
+
+
+
+## Usage
+
+```javascript
+var mskbinary3d = require( '@stdlib/array/base/mskbinary3d' );
+```
+
+#### mskbinary3d( arrays, shape, fcn )
+
+Applies a binary callback to elements in two three-dimensional nested input arrays according to elements in a three-dimensional nested mask array and assigns results to elements in a three-dimensional nested output array.
+
+```javascript
+var add = require( '@stdlib/math/base/ops/add' );
+var zeros3d = require( '@stdlib/array/base/zeros3d' );
+
+var x = [
+ [ [ 1.0, 2.0 ], [ 3.0, 4.0 ] ],
+ [ [ 5.0, 6.0 ], [ 7.0, 8.0 ] ]
+];
+var z = zeros3d( [ 2, 2, 2 ] );
+
+var mask = [
+ [ [ 0, 1 ], [ 0, 0 ] ],
+ [ [ 1, 0 ], [ 0, 1 ] ]
+];
+
+var shape = [ 2, 2, 2 ];
+
+mskbinary3d( [ x, x, mask, z ], shape, add );
+// z => [ [ [ 2.0, 0.0 ], [ 6.0, 8.0 ] ], [ [ 0.0, 12.0 ], [ 14.0, 0.0 ] ] ]
+```
+
+The function accepts the following arguments:
+
+- **arrays**: array-like object containing two input nested arrays, an input nested mask array, and one output nested array.
+- **shape**: array shape.
+- **fcn**: binary function to apply.
+
+
+
+
+
+
+
+## Notes
+
+- The function assumes that the input and output arrays have the same shape.
+
+
+
+
+
+
+
+## Examples
+
+
+
+```javascript
+var discreteUniform = require( '@stdlib/random/base/discrete-uniform' ).factory;
+var bernoulli = require( '@stdlib/random/base/bernoulli' ).factory;
+var filled3dBy = require( '@stdlib/array/base/filled3d-by' );
+var zeros3d = require( '@stdlib/array/base/zeros3d' );
+var add = require( '@stdlib/math/base/ops/add' );
+var mskbinary3d = require( '@stdlib/array/base/mskbinary3d' );
+
+var shape = [ 3, 3, 3 ];
+
+var x = filled3dBy( shape, discreteUniform( -100, 100 ) );
+console.log( x );
+
+var y = filled3dBy( shape, discreteUniform( -100, 100 ) );
+console.log( y );
+
+var mask = filled3dBy( shape, bernoulli( 0.5 ) );
+console.log( mask );
+
+var z = zeros3d( shape );
+console.log( z );
+
+mskbinary3d( [ x, y, mask, z ], shape, add );
+console.log( z );
+```

+/**
+* Applies a binary callback to elements in two three-dimensional nested input arrays according to elements in a three-dimensional nested mask array and assigns results to elements in a three-dimensional nested output array.
+*
+* ## Notes
+*
+* - The function assumes that the input and output arrays have the same shape.
+*
+* @param {ArrayLikeObject>} arrays - array-like object containing two input nested arrays, an input nested mask array, and one output nested array
+* @param {NonNegativeIntegerArray} shape - array shape
+* @param {Callback} fcn - binary callback
+* @returns {void}
+*
+* @example
+* var ones3d = require( '@stdlib/array/base/ones3d' );
+* var zeros3d = require( '@stdlib/array/base/zeros3d' );
+* var add = require( '@stdlib/math/base/ops/add' );
+*
+* var shape = [ 2, 2, 2 ];
+*
+* var x = ones3d( shape );
+* var y = ones3d( shape );
+* var z = zeros3d( shape );
+*
+* var mask = [
+* [ [ 0, 1 ], [ 0, 0 ] ],
+* [ [ 1, 0 ], [ 0, 1 ] ]
+* ];
+*
+* mskbinary3d( [ x, y, mask, z ], shape, add );
+*
+* console.log( z );
+* // => [ [ [ 2.0, 0.0 ], [ 2.0, 2.0 ] ], [ [ 0.0, 2.0 ], [ 2.0, 0.0 ] ] ]
