Matrix Calculator: Solve Matrices Easily & Quickly

[fresh_42]

For all who need to deal with matrices from time to time, I have found a nice tool to calculate with matrices.

This could also be phrased as: Check our Calculator thread from time to time:

I made this extra thread, as the calculator above could handle:

Thanks Fresh! I often use Freemat, a Matlab clone that can handle these kinds of calculations too.

I am fond of the Matlab android app, which is free and comes with the symbolic math toobox. It is very helpful, except during an exam.

I think it requires an internet connection and so may not work under all conditions. Also any work you put in gets sent back to the server which is something you may not want to do all the time. But still its good to know about and to have around.

They mention this note:

I liked that you don't need to know any syntax with the link above. Just type in the fields and go, even with variables: quick and easy.
