# Problem using matlab2tikz

I'm trying to get matlab2tikz to work. I want to use it for prettyfying output of Matlab's image() command.

In Matlab I tried

imagesc(rand(100));
xlabel('X');
ylabel('Y');
title('Random Colors');
matlab2tikz('image.tikz');


but when I do

\usepackage{pgfplots}
\input{../../../../src/image.tikz}


it get error

ERROR: Package pgfkeys Error: I do not know the key '/tikz/y dir' and I am going to ignore it. Perhaps you misspelled it.


Also when I try the matlab2tikz recommended settings

\pgfplotsset{compat=newest} % For best results


I get a similar error

ERROR: Package pgfkeys Error: I do not know the key '/pgfplots/compat' and I am going to ignore it. Perhaps you misspelled it.


How do I determine if my pgfplots version is too old? I'm on Ubuntu 11.10. The latest version of pgfplots itself is 1.5.
