add CAS

[tino1003870]

To replace a TI-Nspire, is the a chance to add some algebra funcionality to this golden piece of software in future?

Hi @tino1003870 I am not too familiar with TI-Nspire. Could you please write more detailed which functionality do you need? Some examples how does it look on TI-Nspire will be also helpful.

Hi Mikhail,

ignore NSpire ... GIAC is at least the same or better equivalent (https://www-fourier.ujf-grenoble.fr/~parisse/giac.html)

Best, Tino

Hi @tino1003870 the library is not a problem. I use internally Apache Common Math library that also have different algebra functionality... I asked about use cases that are helpful for the end users... Could you just list which algebra functionality is missing and can be helpful for the users?

Hi Mikhail,

got it. The following would help a lot (listed in priority order): (1) unit handling (https://www-fourier.ujf-grenoble.fr/~parisse/giac/doc/en/cascmd_en/node609.html) (2) nsolve (https://www-fourier.ujf-grenoble.fr/~parisse/giac/doc/en/cascmd_en/node593.html) (maybe 3) solve, csolve, desolve (https://www-fourier.ujf-grenoble.fr/~parisse/giac/doc/en/cascmd_en/node522.html)

Does it help?

Best, Tino

Hi @tino1003870

my app is already able to handle units. For documentation, please take a look on the files units_overview.mm and units_of_information.mmt from the "Resources of microMathematics Plus". To open resources, use "Open file" from main menu, than press "Home" button, and, finally navigate to the "Resources of microMathematics Plus".

Internally, I use Apache Common Math library that also provides a lot of different algorithms. It also has a good algorithms for the root finding: https://commons.apache.org/proper/commons-math/userguide/analysis.html If I will add something like root solving for a function of one argument, I will prefer Apache Common Math since it is API-compatible. I do not see any cheap possibility to use a C++ library in my app.

Currently, no plan to fix it
