i am trying to execute these commands but i am getting this error "Not enough input arguments."

i am executing the switch statement with the function.

function f=func(x,fun_num)
[ps,d]=size(x);

%fun_num=1   Parameter Estimation for Frequency-Modulated (FM) Sound Waves,initialization range=[0,6.35], bound=[-6.4,6.35] , length of x=6.

switch fun_num
  case 1
         if d<6
            disp('dimension-size should be six.')
         else
         if d>6
            disp('dimension-size is more than 6.')
            disp('function has been evaluated on first six dimensions.')
         end
         end
       theta=2*pi/100;
       f=0;
         for t=0:100
             y_t=x(1)*sin(x(2)*t*theta+x(3)*sin(x(4)*t*theta+x(5)*sin(x(6)*t*theta)));
             y_0_t=1*sin(5*t*theta-1.5*sin(4.8*t*theta+2*sin(4.9*t*theta)));
             f=f+(y_t-y_0_t)^2;
         end

How are you calling the ‘func’ function?

What line of what script or function is throwing the error? Copy and paste the entire red text from the Command Window to your original Question or a Comment to it.

calling of function func

Fitness(i)=func(Sol(i,:));

error

Error using bat func line(switch fun_num)
Not enough input arguments.

Error in bat line()
Fitness(i)=func(Sol(i,:));

[Star Strider]

Your ‘func’ function requires two arguments:

func(x,fun_num)

You have to figure out what to give it for each argument.
