fminsearch error 'Argument 3 must be an options structure'

Greatings to all respected Matlab commuity!

I am working on adsorption isotherm modeling.

When I execute this command to find optimal values I obtained an erro

[a_optimal,options] = fminsearch('residual',a,options,[],f,p,cmu);

'Argument 3 must be an options structure'. If focus on the options is placed as third argument.

Can any please help me regarding this

f = is the function

p, cmu = Arguments to be passed to f.

a = is an array of initial guess comprising of 3 varables uses in the f

a = [0.2, 1, 0.9]

start_time	= cputime;
		options(2)			= tol; 	% TERMINATION TOLERANCE FOR A
		options(3)			= tol; 	% TERMINAL TOLERANCE FOR THE FUNCTION RESIDUAL
		options(14)			= max; 	% MAXIMUM NUMBER OF ITERATIONS	
	[a_optimal,options]	= fminsearch('residual',a,options,[],f,p,cmu);

You need to create options using optimset function

Is it possible if yo give an example here,

I am new here, thereby, need to time to understand things

Click on the link I gave there are examples there.

Can you please check how can I implement the optimset in this code.

I don't want to. @Hafiz Muhammad Asfahan Please don't dump the code with a lot of irrelevant information.
