MATLAB MATLAB: Importing Files and Creating Contours

[MathematicalPhysics]

Hey! I am using c++ to simulate charges dissipating. I've written the output to a file in the form of a matrix, so in the file is just a matrix of numbers showing equipotentials etc.

I want to show the contours by using MATLAB. I'm not used to working in MATLAB but I tried! I clicked file --> import data, then pointed it to the output file from c++ (just a .txt file).

After clicking next a few times it appears to have imported the correct file.

Now what do I do? Reading textbooks, I gather its something like:

>contour(...)

Im really not sure about this! I hope I don't have to start learning MATLAB from the beginning just to work this out! The point of my project is to use c++ to work out the charge dissipation, which I've done but wouldn't it be nice to have some pictures?!

Thanks in advance,

Matt

You can writte "help contour" on the command window.
