I want to minimize a function f: which has a single variable θ. I want to minimize the function so I want to use the command "fminbnd". Although I want to see the iteration display through "optimoptions". If I write a chunk of code like this
fun = @(theta) optimum_theta(alpha,snr_db(isnrdb),t_min,t_max,m,theta);
options = optimoptions('fminbnd','Display','iter'); % show iterations
[x fval exitflag output] = fminbnd(fun,lower_bound,upper_bound,options);
Here the chunk of code I am not getting how to proceed

Note that fminbnd is not provided as part of the optimization toolbox. As well, fminbnd has been around a long time. So optimoptions does not support fminbnd. (I suppose there are good arguments as to why it should. But it apparently does not.)
Use optimset instead.
fun = @(x) (x-pi).^2; % not very creative
opts = optimset('fminbnd');
opts.Display = 'iter';
[x fval exitflag output] = fminbnd(fun,0,10,opts)
Note: you would have learned that quickly had you read the docs for fminbnd, where you would see that it uses optimset.
