Calculate distance between 2 points using array
显示 更早的评论
Hi, how can I find the distance between 2 points using this equation? eqn=sqrt{{X_{i+1}-X_{i}}^2+{{Y_{i+1}-Y_{i}}^2}};
I need to use a matrix that is defined by the user (it cannot be changed) so any coordinates can be entered.
numberOfCoord=input('Please Input the Number of Coordinates:');
if numberOfCoord < 4
disp (['Error']);
return
end
data = zeros(2, numberOfCoord);
for i= 1:1:numberOfCoord
data(1, i)=input('Please Enter X Coordinate:');
data (2, i)=input ('Please enter Y Coordinate:');
end
if i < 0
disp (['Error']);
return
end
any tips or help to solve this would be great thanks :))

This code requires atleast 4 points, are you looking for distances from a given point to every other point?
