Matrix calculator

[fredsie]

Hi, I'm looking for a (preferably online) calculator which will convert a matrix to row-echelon form, but can't seem to find one. There seem to be lots that do other matrix calculations.

(Sorry, couldn't find a more suitable category here for a maths question than Science) .

Cheers.

A bit more effort and I've found an excellent one, at:

I need to improve my choice of Google search keys!

Regards all.

Mathematica can do this for you, and I assume MatLab and Maple can do too. They're pretty expensive though.

Sage is a set of free tools similar in vein to the above, which will also be able to perform this operation.

(All running on your computer. Vastly more useful and probably faster if you're doing this a lot / with a very large matrix.)

Many thanks. Matlab and co are a bit out of my price range but I'll have a look at Sage. You're right about the speed etc of the online calculators, with a 6x7 matrix I couldn't get the process to complete.

Post it here and I can compute it if you like.

Sage uses Maxima I think, for analytical stuff.

Mathematica is my favourite for analytical stuff, and is �80 for a student license. Still a high price, but far less than the usual price.

Thanks for the offer, but it wasn't a particular matrix. I'm working through a Linear Algebra course and wanted to check the results I was getting manually.
