If values are approxximately the same plot one function, if not plot two

Hello, I have a two vectors with calculation results. Has someone of you an idea how can I compare results of this two vectors and if all values are similar (ex. ~0.5 for each value) matlab will plot one function (plot(vec1,x)) and if difference is greater two functions (plot(vec1,x) and plot(vec2,x))?

Thank you

Presuming the 'all' in "if all values are similar" means a pointwise comparison between the two vectors of same length, then

if all(abs(v1-v2)<delta) % set delta as desired
  plot(x,mean([v1 v2])   % use average of the two instead of just one
else
  plot(x [v1 v2])
end

I've also assumed v1;v2 are column vectors and that x is the independent variable. Altho I suppose, mayhaps it could be t'other way 'round in which case reverse the order of the arguments to plot

Your all assumptions are correct. Unfortunately I am not able to find delta that will work as I want. I try very small and also bigger values but its still showing plots wrong (sometimes even if both function looks identical it plots both of them)

Maybe there is another way?

The parentheses were wrong. Must be

   all(abs(v1 - v2) < delta)

Yup, sorry..."air code" is prone to typos...
