{{alias}}( arrays, shape, strides, fcn ) Applies a quaternary callback to strided input array elements and assigns results to elements in a strided output array. The `shape` and `strides` parameters determine which elements in the strided input and output arrays are accessed at runtime. Indexing is relative to the first index. To introduce an offset, use typed array views. Parameters ---------- arrays: ArrayLikeObject<ArrayLikeObject> Array-like object containing four strided input arrays and one strided output array. shape: ArrayLikeObject<integer> Array-like object containing a single element, the number of indexed elements. strides: ArrayLikeObject<integer> Array-like object containing the stride lengths for the strided input and output arrays. fcn: Function Quaternary callback. Examples -------- > var x = new {{alias:@stdlib/array/float64}}( [ 1.0, 2.0, 3.0, 4.0 ] ); > var y = new {{alias:@stdlib/array/float64}}( [ 1.0, 2.0, 3.0, 4.0 ] ); > var z = new {{alias:@stdlib/array/float64}}( [ 1.0, 2.0, 3.0, 4.0 ] ); > var w = new {{alias:@stdlib/array/float64}}( [ 1.0, 2.0, 3.0, 4.0 ] ); > var u = new {{alias:@stdlib/array/float64}}( [ 0.0, 0.0, 0.0, 0.0 ] ); > var shape = [ x.length ]; > var strides = [ 1, 1, 1, 1, 1 ]; > function f( x, y, z, w ) { return x + y + z + w; }; > {{alias}}( [ x, y, z, w, u ], shape, strides, f ); > u <Float64Array>[ 4.0, 8.0, 12.0, 16.0 ] {{alias}}.ndarray( arrays, shape, strides, offsets, fcn ) Applies a quaternary callback to strided input array elements and assigns results to elements in a strided output array using alternative indexing semantics. While typed array views mandate a view offset based on the underlying buffer, the `offsets` parameter supports indexing semantics based on starting indices. Parameters ---------- arrays: ArrayLikeObject<ArrayLikeObject> Array-like object containing four strided input arrays and one strided output array. shape: ArrayLikeObject<integer> Array-like object containing a single element, the number of indexed elements. strides: ArrayLikeObject<integer> Array-like object containing the stride lengths for the strided input and output arrays. offsets: ArrayLikeObject<integer> Array-like object containing the starting indices (i.e., index offsets) for the strided input and output arrays. fcn: Function Quaternary callback. Examples -------- > var x = new {{alias:@stdlib/array/float64}}( [ 1.0, 2.0, 3.0, 4.0 ] ); > var y = new {{alias:@stdlib/array/float64}}( [ 1.0, 2.0, 3.0, 4.0 ] ); > var z = new {{alias:@stdlib/array/float64}}( [ 1.0, 2.0, 3.0, 4.0 ] ); > var w = new {{alias:@stdlib/array/float64}}( [ 1.0, 2.0, 3.0, 4.0 ] ); > var u = new {{alias:@stdlib/array/float64}}( [ 0.0, 0.0, 0.0, 0.0 ] ); > var shape = [ x.length ]; > var strides = [ 1, 1, 1, 1, 1 ]; > var offsets = [ 0, 0, 0, 0, 0 ]; > function f( x, y, z, w ) { return x + y + z + w; }; > {{alias}}.ndarray( [ x, y, z, w, u ], shape, strides, offsets, f ); > u <Float64Array>[ 4.0, 8.0, 12.0, 16.0 ] See Also --------
