Hi I have a contour plot with two sets of contour lines and the label of the value on each of the contour lines. does anyone know how to edit these labels as I want to add the unit of each value? For some reason when I manually edit the plot I can only do this for one set of contours not the second set.
thank you

Use the return value functional form
[C, H] = contour(...) returns contour matrix C as described in
CONTOURC and a handle H to a contourgroup object. This handle can
be used as input to CLABEL.

thanks so that means
A = contour(cost)
h = ['test1','test2','test3']
clabel(A,h,'FontSize',15,'LabelSpacing',3000)
?

No, the handle referred to is the optional second return value H which you didn't return...you returned the contour matrix C in A
