MATLAB: “solve” Function

equationMATLABsolve

I'm trying to use the "solve" function to find a variable, but the other variables in the equation are input as opposed to defined. How do I fix this? Here's to illustrate what I'm trying to do using a simplified equation:
x=input('x = ')
y=input('y = ')
z=solve('x+y=z',z)

Did you solve the license problem? Until you have the software installed and licensed, solve() isn't going to work.
The answer you are looking for is along these lines:
syms x y z
xin = input('x =');
yin = input('y =');
zsol = solve('z-y=x', z);
disp(['z = ' char(zsol)]);
znum = double(subs(zsol, {x, y}, {xin, yin}));
disp(['z = ' num2str(znum)]);
