grid calculator

This is what it says. It operates on loaded grids but you can also load more grids (as long as they are GMT grids). When grids are loaded in memory they will show up in the lower box area. Double-click on a name to move it to the command area. The syntax used is that of Matlab. This means that in principle any Matlab single command that produces a 2D array can be used to produce a new image. eg: sin ( 10 * (repmat( linspace(-pi,pi,201),201,1).^2 + repmat(linspace(-pi,pi,201)',1,201).^2) ) Notice that we had to use repmat instead of meshgrid as we usually would do because we need to produce the output array in one single command like I said above.

This option is not available in the compiled version.
