Like there is fplot for plot, is there a function that replaces semilogx, semilogy, loglog for symbolic functions, because semilogx, semilogy, and loglog aren't working for my symbolic functions.
Please share, thank you.

Use the set function with fplot to adjust the axis scaling:
syms x(t)
x(t) = exp(-2*t);
figure(1)
fplot(x, [0 10])
title('Linear x')
figure(2)
fplot(x, [0 10])
set(gca, 'YScale','log')
title('Semilogy x')
