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.

Hi thank you for your plug-in I hope it will be useful for most of OpenOffice.orgs´users.

Please do comment on this extension, because it will be very useful to me as a new developer!!!

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

Please consider that I've commented like above caz of a comment that have been posted here. But that person has deleted it after my comment.
Feel free to post useful things.. :)

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!!

I will sooner update the extension with a Help option.

Please consider following short cuts:

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

Switch between cells using TAB

Thank you!!

Extremely sorry I did a mistake while posting the short cut keys...
