This page contains examples that show APL's strengths. The examples require minimal background and have no special dependencies. If these examples are too simple for you, have a look at our advanced examples.

APL has very sophisticated plotting/graphing & with a little effort we can make a grid line plot. (Y axis:the odds for # 1-66 by X axis:the # 1-66) You can see below for example that for 40 people the odds is about 90%. Plotting all possible odd shows a curve not a straight line.

Example using APL to index ⍳ or find (or not find) elements in a character vector: First, variable Letters is assigned a vector of 5-elements, in this case - letters of the alphabet. The shape ⍴ or character vector-length of Letters is 5.

APL (named after the book A Programming Language) [3] is a programming language developed in the 1960s by Kenneth E. Iverson. Its central datatype is the multidimensional array. It uses a large range of special graphic symbols [4] to represent most functions and operators, leading to very concise code.

APL is an array language, and one of the oldest programming languages still in use today, next to FORTRAN, Lisp and COBOL. APL uses its own curious-looking symbols, like ⍎⌽⍕⌈* ≡⍬, rather than reserved words written out in English like most other languages, like C or Python.

This page contains a listing of more involved examples that show APL in action. While they are fully explained, a basic grasp of APL will greatly help you understand them. If these examples are too complex for you, have a look at our simple examples.

Some of the best resources for somebody new to APL and programming in general are: Follow one or a couple of these tutorials through and play around a bit. To learn APL the advice is similar to that for learning other languages: have a goal (something you want to accomplish) and try to do it.

what is meant by that. And, when someone implies that the APL way is better, or that APL is a better language for thinking about problems, we must ask how APL helps (or hi. ders) problem-solving. Specifically, just what is unique of special or different a. out thinking with APL? Such questions motivate us to study how APL affec.

In APL you can easily create a program to calculate the formula like this: birthdaysame←{⎕FR←1287 ⋄ 1-(!365)÷(365*⍵)×(!365-⍵)} The ←⎕FR←1287 tells apl to do this in double precision arithemic which is needed because …
