constrain in fmincon exceeds its maximum, any tip?

Hi, I have many constraints in my file but one is not fulfilling the given condition. When i run the model I get the values that exceeds max_capacity and I do not want that.

Can anyone let me know where is the error maybe? Thank you a lot!

% So constaint is of a form A*x <= b

    ot = ones(N,1);
    ot1 = ones(N,1)*k2; %k2 is a scalar
for i=1:M % number of case studies
    A2 = spdiags([ot1 ot],[0 N],N,N*2);   
end
for i=1:M
    b4(1:N,i)=max_cap(1,i); %max capacity 
end 
A = [A; A2]; %just addition to previous vector constraints
b = [b; b4]; %just addition to previous vector constraints

and I am optimizing with fmincon on x.

The equation in respect to fmincon is:

% % k2*H*x<=max_cap

Should I also include H in calculation in constraint?

H is of a form= (S(t)/alpha_par).^(1/b_par(i)))

Thanks a lot!
