fimplicit3 error: Array sizes must match
显示 更早的评论
Hello everybody!
I have a problem with the function fimplicit3.
I try to plot simple surfaces as x^2 + y^2 - z^2 using two lines of code:
syms x y z
fimplicit3(x^2 + y^2 - z^2)
and no matter wich surface I want to plot it returns me the same error everytime! Even if i try the script in thet MATLAB help section inside the program.
This is the message that i get everytime I try: "Warning: Error updating ImplicitFunctionSurface
Array size must match."
What can I do ? Thanks for your help!

I tried your code in my machine, it is working fine. Also as a suggestion try to use
fimplicit3(x.^2 + y.^2 - z.^2)
instead of ^2.
Try to run it using a function handle like below
f = @(x,y,z) x.^2 + y.^2 - z.^2;
fimplicit3(f)

That sort of sudden change can happen sometimes if you accidentally create function with the same name as an internal Mathworks function.
Try using
restoredefaultpath
and then executing your code; if it works then something on your path was the problem.

Which MATLAB version are you using?

My guess is that you had already defined x,y, or z so clearing all your variables solved the problem.
