I have large data (2Gb) that I have troubles plotting with pcolor or surf ?
How can I save an jpeg image of contour map plot like pcolor with my color map ? I cannot plot the pcolor fig file.

You don't have a 2 GB screen so it doesn't make sense to try to plot the whole thing with surf. Try subsampling the data and then calling surf on the subsampled data. To save a contour plot, try export_fig.
