As is shown in this graph,
whenever I use some "syms" command, it goes wrong.
How could I solve it? Thank you in advance

I have used syms function frequently before, without any problem showing up.
But recently, it turns out to be erroneous. What should I look at about the function

syms creates an Inf value as part of its operation, and you've enabled an error breakpoint that causes MATLAB to enter debug mode when it encounters Inf or NaN. Clear that error breakpoint so MATLAB doesn't try to stop inside the syms function (technically the symvar function, which syms calls.)

I have many times wished I could say "No, don't stop in this function for inf !"
