About Euclideus Pro

Euclideus Pro is a software application designed to assist engineers, scientists, mathematicians, programmers -- anyone engaging in a technical discipline. It allows for the evaluation and graphing of advanced mathematical operations, such as numerical integration, analytical differentiation, Fourier series, and more on a phone or tablet. While a complete product manual is included in the application itself (Menu button -> Instructions), below is a list of Euclideus Pro's key features:

- the Pro version of Euclideus adds advanced graphing interfaces for 1D and 2D graphing that nicely complement the main mathematics interface, allowing you to generate complex-valued plots of your functions and expressions.

- Euclideus is based on complex-valued arithmetic from the ground up, such that its basic functions and arithmetic assume that quantities are complex;
- it performs advanced numerical operations such as integration, root- and peak-finding, and prime-number decomposition;
- it analytically evaluates derivatives of functions and expressions;
- you can assign variables and multi-valued functions, for use in other expressions, similarly to more advanced commercial scientific software packages;
- it can evaluate several special functions, such as Airy and Bessel functions, and associated Legendre polynomials;
- it can perform Nth order polynomial regression (and outputs error estimates on parameters) of a set of data points;
- it converts between binary, hexadecimal and decimal numbers (including fractional numbers);
- Euclideus worksheets (which include all assigned variables and functions, together with the input history) may be saved to and loaded from the file system;
- press the Android Menu button, then "Instructions" for a complete product manual;

Euclideus is an excellent tool for performing advanced analysis on-the-go, where a computer is not readily available.

Euclideus will always be free, every coffee inspires new ideas!

What’s new in Euclideus Pro

Updated engine to postpone lambda evaluation, e.g. lam = :return=x, return=return^4; <---- lambda is stored but not evaluated lam.eval() <----- evaluates the lambda Implemented general functions of a matrix: mat.func(:this^-sqrt(this);) will evaluate the lambda expression for a matrix mat -- where the identifier "this" refers to the parent object
