Welcome to FrAid 1.5

Introduction

Welcome to FrAid, the lightweight scripting environment for mathematical computations and vizualization.

To execute your first FrAid program just download and install FrAid and depending on the operating system execute fraid.sh (Linux) or fraid.bat (Windows). This will open up a FrAid Console where you can open, type or copy/paste your scripts. Some ideas of how FrAid can be used can be seen in the gallery and demo pages.

FrAid Applications

What is different about FrAid

There are several systems out there similar to FrAid but this is what makes FrAid unique:

  • FrAid emphasizes simplicity. The only mathematical abstraction it deals with are n-dimensional Complex functions - f:Cn→C, which is enough for most practical purposes. You do not have to deal directly with vectors and matrices (which anyways are just special cases of functions and systems of equations) yet you can work with transformations, linear and nonlinear systems of equations, n-dimensional differential equations, etc.
  • FrAid (the language) is simple. With only three reserved words "if", "then" and "else" (if we do not count the operators and special symbols) and Mathematics-like function notation, FrAid should be easy to learn and use for people with interest in mathematcis or its applications but no free instagram followers experience in programming.
  • FrAid is dynamic. Every change in a user defined function make money on ebay or variable is immediately reflected in all FrAid objects (other functions, plots, etc.) which depend on this function or variable.
  • FrAid is recursive. Like all mathematical functions FrAid carpet cleaning katy tx functions can be recursive.
  • FrAid is extensible. It is easy to write and preload your own FrAid functions or Java implemented library functions and FrAid graphics plugins. In fact you can dallas carpet cleaning replace all standard FrAid operators (+, -, *, /, etc.) with your own because they are just Java implemented library functions.
  • FrAid offers a lightweight extendable interface for f:Cn→C to your Java programs.
  • FrAid graphics has "infinite" zooming capability. Which might be important if you work with fractals or other high detail graphics.
