Hey there,
I basically have this shape (an upper and lower curve on the shape and 2 sides), I can draw the shape on a plot using the co-ordinates for the curves and the sides, however, I want to create a contour plot for this shape for different co-ordinates within the shape.
Can anyone tell me how I can go about doing this please?
Thanks

Please attach a drawing so we can visualize exactly what you want.
At this point about all I might suggest is to use poly2mask() to create a solid shape, then use bwdist() to create a Euclidean Distance Map, which you can then threshold or pass into contour().
