# Graphing the difference of two handle-functions in matlab

I have two handle-functions, their graphs are very close to each other, I can see this by plotting both functions.

f = @(x1); ff = @(x2); fplot(f, [0 1],'r') hold on fplot(ff, [0 1],'b') hold on

I would like to have another graph where I take the difference between f-ff

fplot((f-ff), [0 1])

how can I do this in matlab? And how can I find the:

max(abs(f-ff))

when both are handle-functions? Thanks in advance!

PS. Just let me know if I should add more info about f and ff.

Try this:

fplot(@(x) f(x) - ff(x), [0 1])
