{{APL | [[Reduction]] and the related operators [[Scan]] and [[Windowed Reduction]] reduce along 1-dimensional subarrays of the right argument. The vectors used in a particular reduction can be formed by taking a scalar index along each axis except the reduction axis, and selecting from the reduction axis according to the operator used. For a reduction the entire axis is used while for scans [[prefix]]es are used and windowed reductions take subsections of the length specified by the left argument. | ||
