I am trying to find and plot the values of xSol and ySol by using x and y arrays as follow:
clc
clear all
% DME COORDINATES
x1= 2; y1= 10; % DME 1
x2= 15; y2= 30; % DME 2
x3= 20; y3= 3; % DME 3
% ASSUMED POSITION OF OBJECT
x = [10,25,31,35,40];
y = [20,30,41,49,56];
% DISTANCE OF OBJECT TO DMEs
r1 = sqrt((x-x1).^2+(y-y1).^2);
r2 = sqrt((x-x2).^2+(y-y2).^2);
r3 = sqrt((x-x3).^2+(y-y3).^2);
% EQUATIONS
syms x y
eqn1 = 2*x*(x2-x1)+2*y*(y2-y1) == (r1.^2) - (r2.^2) + (x2.^2) - (x1.^2) + (y2.^2) - (y1.^2);
eqn2 = 2*x*(x3-x1)+2*y*(y3-y1) == (r1.^2) - (r3.^2) + (x3.^2) - (x1.^2) + (y3.^2) - (y1.^2);
sol = solve([eqn1, eqn2], [x, y]);
i=length(x);
j=length(y);
for k=1:i
xSol = sol.x(k);
end
for m=1:j
ySol = sol.y(m);
end
plot(xSol,ySol,'LineWidth',4)
But it gives me error saying index exceeds. Kindly help!
