I'm not sure why I keep getting the following error messages:
Array indices must be positive integers or logical values.
Error in hehemouse (line 13)
dx=x(mod(i+1,5))-x(i)/sqrt(((x(mod(i+1,5))-x(i))^2)+((y(mod(i+1,5))-y(i))^2));
My code is the following.
% Initialize the positions of the 5 mice
x = [0, -sin(2*pi/5), -sin(4*pi/5), sin(4*pi/5), sin(2*pi/5)];y = [1, cos(2*pi/5), -cos(pi/5), -cos(pi/5), cos(2*pi/5)]; % For each iteration, each mouse moves a distance d=0.01 towards neighbour ccw
% To find mouse's neighbour, just do (x+1)%5 = generate coordinates
% Repeat iterations until mice are sufficiently close to each other
while ((sqrt((y(2)-y(1)^2))+(x(2)-x(1))^2)>0.01) for i=1:5 fprintf('%lf %lf', x(i), y(i)); dx=x(mod(i+1,5))-x(i)/sqrt(((x(mod(i+1,5))-x(i))^2)+((y(mod(i+1,5))-y(i))^2)); dy=y(mod(i+1,5))-y(i)/sqrt(((x(mod(i+1,5))-x(i))^2)+((y(mod(i+1,5))-y(i))^2)); x(i)=x(i)+0.01*dx; y(i)=y(i)+0.01*dy; end end % To graph, store sequence of vectors in matrices with each line representing coordinates at one of the time steps
x = mat(i,:);y = mat(:,i);
