How can I shade or hatch regions bounded by contour lines, to distinguish feasibility zones from constraint zones in a contour plot?

Hello,

I want to produce a figure similar to this one below. The lines would be from 2 or more functions which represent equal contour levels.

How can I produce the hatched / shaded zone, which is bounded by contour lines?

Thanks

You can use some file exchange functions.

Also you can fillyour required color using fill, patch.

Hi, these do not fill in between seperate lines produced by seperate calls of a contour function
