apl APL a Day #7: Scalar Functions Scalar functions perform most of the hard labor in an APL program. A scalar function defines a mapping from one or two scalar values to a third value. In math, the addition function
apl APL a Day #6: Indices and Encoding Previous sessions established a basic conception of indexing an array. Namely, an index encodes a reference to an element in an array according to the position of the element along each of its
apl APL a Day #5: Indexing into Arrays By now, clearly a shape and vector of values precisely determines an array. All APL functions operate over arrays; they describe new arrays in terms of its arguments. What about describing a sub-array
apl APL a Day #4: Arrays have elements An array that only describes a box which may contain elements, but that does not contain any elements, does not mean much. While shapes help to clarify the APL language, when doing any
apl APL a Day #3: Arrays have Shape Arrays arrange data into a certain rectangular shape. In APL, the shape of an array is a vector --- yes, in APL, shapes are also arrays --- that describes the number and size
