How to plot symbolic function with too many variables

Hello,

I am new in this Matlab world and I have to understand some things.

How can I plot an equation like this?

>> sol_h.T

ans =

C2 - t*(T*alpha2 + T*gamma1 + 100*T*k3 - 200*U*k1 + (40000*U^2*k1^2*pT)/A2 - (40000*U^2*k1^2*pU)/A2)

I got the numerical values and I wrote them in the code like:

alpha2 = 0,001;

But I would like to replace the variable with the numerical values in the equation. How can I?

Thank you so much, have a good day!

Use subs() to substitute values, symbolically you can plot with max three values(since 2016b I suppose).
