Error Message while executing these function - Unbalanced or unexpected parenthesis or bracket

Hi, While running the main.m, I am getting unbalanced or unexpected parenthesis or bracket error. Appreciate your help.

Don't use subscripts in function argument lists. I.e., don't use the (1) and (2) below:

function [AA1,AA2] = distributingthepoints(n,d_w,d_h,obstacle_all(1),obstacle_all(2))

This should look something like this instead:

function [AA1,AA2] = distributingthepoints(n,d_w,d_h,obstacle_all)

Then you can use subscripted values obstacle_all(1) and obstacle_all(2) inside the function.

Having said that, however, it looks like there will be an argument mismatch in this call:

[A0]=distributingthepoints(n,d_w,d_h,cl1,cl2,obstacle_all);

The number of arguments will not match up with the function. Maybe you can just eliminate the cl1 and cl2 since it doesn't appear they are used inside your function.

Appreciate your help. Let me try it now. Thanks for your help.

I am still getting same error msg after fixing argument mismatch. I am suspecting error in these code but not sure. appreciate your feedback.

     X(i,1)=[obstacle_all(1):0.1:obstacle_all(1)+d_w];

     X(i,2)=[obstacle_all(2):0.1:obstacle_all(2)+d_h];

%distributept.m

function [AA1,AA2] = distributept(n,d_w,d_h,obstacle_all)

A1=[];A2=[];

for I=1:n

    for i=1:length(obstacle_all)

     X(i,1)=[obstacle_all(1):0.1:obstacle_all(1)+d_w];

     X(i,2)=[obstacle_all(2):0.1:obstacle_all(2)+d_h];

     for j1=1:length(X(i,1))

        a1=[obstacle_all(1),X((i,1)j1)]; 

         A1=[A1;a1];

     end

        for j2=1:length(X(i,2))

           a2=[obstacle_all(2),X((i,2)j2)]; 

        end

        A2=[A2;a2]; 

    end

end end
