Numerical simulation with symbolic expressions

Hello, I’m a beginner with octave, never used, and I would like to compute some things.

I have long symbolic expressions and I would like to compute the output of the functions for a set of parameters included in the function which may vary between an interval.

for example I’d like to compute this function for the parameters which may range between an interval or else

thanks for your help,

syms gamma alpha b
expr = gamma^2*alpha + log(b);
expr = matlabFunction(expr,'Vars',[gamma alpha b]);
gamma = 0:0.1:1;
alpha = 2.0;
b = 5.0;
plot(gamma,expr(gamma,alpha,b))
