I have to plot a bidimensional map of a matrix using 'contour', and what I obtain is plotted in figure.

The problem is that in this way I have discrete lines, while I need to see a continuum between minimum and maximum values, with a gradual change of colors, with no blank spaces. Is it possible to do that? Maybe using a function different from 'contour'? Thanks!

I have about the same kind of image if I try to use contour on my data. Instead I plotted it using 'imagesc'. It works good enough for me (since I just want to see something), but I don't know if it is what you are looking for.

Thank you, now it looks better! Just one question: by using imagesc the image is not at the same position, because the vertical axis is reversed, while I prefer not to reverse it. How can I do it? In the figures below you can see what I mean (the first one is obtained by using contour, the second one with imagesc)
