Figure imported from Matlab to Latex [duplicate]

I have a problem getting a figure from Matlab into Latex. I have saved the figure as a EPS-file in the same folder as I have saved the latex-documents. This is what I wrote in Latex:

\begin{figure}
\includegraphics{diffusion}
\end{figure}


diffusion is the name of the figure. The problem is that when I run this code in Latex, I only get much open space, but no figure. Does anyone have an ide what I should do differently?
