function [O]=fitness(x1,y1,x2,y2,start,goal)
dis=distance(start,goal);
theta=pathsmoothness (x1,x2,y1,y2,goal);
z=dis+theta;
O=1/(z+0.001);
end
function theta= pathsmoothness (x1,x2,y1,y2,goal)
theta1 =atan((y2-y1)/(x2-x1));
theta2= atan(((goal(2))-(y1))/(goal(1)-(x2)));
theta= theta1-theta2;
end
function [dis] = distance(start,goal)
%This function calculates the distance between any two cartesian coordinates.
delta_x=goal(1)-start(1);
delta_y=goal(2)-start(2);
% Calculate the distance to the goal
dis=sqrt(delta_x^2+delta_y^2);
%dis=sqrt((x1-x2).^2 + (y1-y2).^2);
end
Consider Start=[1,1] and goal [10,10]
When I try to call fitness function at the following line in my code. it says to many input arguments.
[particle(i).Cost, particle(i).Sol]=fitness(particle(i).Position);
I dont know how to resolve it.

Your function accepts x1,y1,x2,y2,start,goal........what does particle(i).Position output?

function sol1=createsolution(model)
n=model.n;
Xmin=model.Xmin;
Xmax=model.Xmax;
Ymin=model.Ymin;
Ymax=model.Ymax;
sol1.x=unifrnd(Xmin,Xmax,1,n);
sol1.y=unifrnd(Ymin,Ymax,1,n);
end
THis is particle psoition.
particle(i).Position=createsolution(model)
model is another function in which parameters of robot are given they are as follows:
function model=Makingmodel()
%source
xMR=1;
yMR=1;
%goal
xG=10;
yG=10;
SP=[xMR,yMR];
GP=[xG,yG];
%obstacle=[];
xobs=[3 3];
yobs=[3 3;5 7];
robs=[3 1;4 7;7 9;1 8;9 3;5 6;7 7];
n=3;
Xmin=-11;
Xmax= 11;
Ymin=-11;
Ymax= 11;
model.xMR=xMR;
model.yMR=yMR;
model.xG=xG;
model.yG=yG;
model.xobs=xobs;
model.yobs=yobs;
model.robs=robs;
model.n=n;
model.Xmin=Xmin;
model.Xmax=Xmax;
model.Ymin=Ymin;
model.Ymax=Ymax;
%p.XYMAX=11;
%map=zeros(p.XYMAX,p.XYMAX)+inf;
%map(p.GP(1),p.GP(2))=0;
end
