The MatrixManipulator is addressed to anyone who is following Advanced Mathematics. This can be used as an extension for both Calc & Math. It's really useful to have a way to check your solutions for the problems on Matrices, that encourages me to develop such thing.

I will sooner update the extension with a Help option.

Please refer the following:

Please consider that short cuts should be corrected as follows:

Continue: ALT+c
Back: ALT+b
Exit: ALT+e

Sorry for any inconveniences.


could you please move the menu item from main menu to "Tools > Addons"? It's quite cluttering if every extension puts its own item in menu bar instead of a submenu.

I'll move it from next update onwards!!

Please avoid submitting useless comments!!!
This is really annoying, don't use this to put ur Ads.
