Need help writing a for loop

So I was assigned a project where I wrote a function f that takes inputs q, Tc and T and returns a number according to a chemistry equation. The second part of the assignment was to write a program that loops 50 values of T between 0.5 and 1.3 and finds the value of q that minimises the value of f (using fminsearch) at a given T where Tc always = 1. I wouldn't normally use a loop to do this, but we have to here so here's what I have so far which is probably very wrong but I don't really know how to get it to work. We have to plot a graph of the min q values against the T values but my graph comes back blank.

Thanks for the help.

Ti = 0.5;
Tf = 1.3;
nT = 50;

for iT = 1:nT
    T = Ti + (Tf - Ti)*iT/(nT-1);
    Te(iT) = T;
    qmin = fminsearch(@(q) f(q,1,T), T);
end

plot(T,qmin)

assign to qmin(iT)

plot(Te,qmin)
