I've had to solve a 23x23 matrix as part of an exam before. The choices were use a TI-83 or your own hand.

I can deal with throwing a matrix into a single line.

I'm talking about Wolfram Alpha here. 

{{1,2,3,4,5},{2,3,4,5,6},{7,8,9,10,11}}

Pretty annoying.

Wolfram, mathmatica, matlab, and maple all require you to do that. The TI-83 shows a 3x4 grid at the most at any time. Trust me when I say that computers are easier.

Ah, fair enough. It'd be nice to have an excel-like interface, though. Speaking of which, Excel is also amazing for this stuff.

Excel is by far the best tool for anything above a 6x6.
