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?

在 MATLAB Online 中打开

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
