'syms' and 'gcd' not working in MATLAB 2018a

By typing x = sym('x')

or

syms x gcd(x^3 - 3*x^2 + 3*x - 1, x^2 - 5*x + 4)

from the examples, MATLAB command window remains active without any result. Then, I have to force MATLAB to exit by using the cursor.

Your code works for me.

Note that I already did the update described in: "syms", "sym", and "mupad" functions cause MATLAB to freeze (link).

[Riccardo Bassoli]

Thanks for your answer. I had already checked the link. I had MATLAB 2017a and I experienced the bug. I updated to 2018a and still MATLAB remains busy forever by using sym/syms.

[Star Strider]

My pleasure.

You will also have to install the update in R2018a.

[Riccardo Bassoli]

Ok, with the update works. Thanks for your time! Have a nice day.

My pleasure!
