Posted: Friday, 12.Aug.2011 13:53 Post subject: Integral  calculating mathematical integrals 



"Integral" is an easy to use free and opensource (GPL) application to calculate mathematical integrals with many features :
* undefinite, definite and numerical integration;
* integrals in one, two and three variables (1D, 2D, 3D);
* 5 simplification methods for nonnumerical results;
* 3 numerical integration methods and arbitrary number of digits (default is 15);
* option to show the calculation time;
* option to show the not calculated integral before the result;
* result with zoom levels and different colors;
* 7 output types : simple, bidimensional, typesetting (to be implemented), LaTeX, MathML, C and Fortran;
* copy&paste available in all entry fields and also in the result, allowing copying the result to anywhere;
* history and line completion editing in the integrand, differentials and limits.
See the Integral web site and Integral in MyMaemo Software Catalog.
"Integral" runs on Maemo 4 (Nokia N800/N810), Maemo 5 (Nokia N900) or any smartphone/tablet/computer where Python, SymPy and PyQt are available. Future versions will use PySide and QML.
SymPy is a computer algebra system (CAS) written in pure Python, it is free and open source project, see SymPy.org. SymPy last version (0.7.1, July 2011) is available for Maemo 4 (Diablo) and Maemo 5 (Fremantle). Look at SymPy topic in MyMaemo forum.
Integral v1.1.2 for Maemo 5 (Fremantle) is available in extras repository.
Python, PyQt and SymPy will also be installed if not installed before.
"Integral" is small (50 KB) but it installs "SymPy" (about 18.5 MB after install, with .pyc compiled Python files). "Integral" and "SymPy" are optified on Maemo 5.
Please help promote Integral (v1.1.2 promoted in 01/11/2011) and SymPy to extras repository by voting in :
Integral 1.1.2fremantle2
See also "Derivative" and "Limit", which calculate mathematical derivatives and limits :

Derivative in MyMaemo Software Catalog
Limit topic in MyMaemo forum.

New versions of Integral were recently released. Here the change log of them :
(20110811)
Integral v1.0.0 for Maemo 5 (Fremantle) :
* 1st public release on extrasdevel repository;
* uses SymPy 0.6.6 (12/2009);
* time to load is approx. 7 seconds on Nokia N900 @ 600 MHz.
(12/09/2011)
Integral 1.1.0 :
* uses new version 0.7.1 (07/2011) of SymPy;
* bidimensional output type has correct line breaks without opening the X Terminal;
* result with zoom in and out in 8 levels;
* different colors for calculation time, noncalculated integral and result;
* 5 simplification methods instead of 3;
* Fortran output type;
* help window;
* more robust input;
* time to load is approx. 7 seconds on Nokia N900 @ 600 MHz.
(14/09/2011)
Integral 1.1.1 :
* to show greek and other symbols in bidimensional output the X Terminal is opened when starting Integral and can not be closed.
(15/09/2011)
Integral 1.1.2 is now available in the extrasdevel repository :
* no need anymore of X terminal being opened to show greek and other symbols in bidimensional output.

Apologies for the delay! It's because I was working on the Harmattan Software catalog. But in the next days I will update the Maemo catalog as well.

Corrected the time to open Integral on Maemo 5 (Nokia N900), about 7 s instead of 23 s. It is faster due to byte compiling of Python files of last SymPy package version.
