Hi there, I have a start position, start = [1,2]; and an end position, endpos = [8,8];. How can I calculate the distance left to travel for each time interval, for example each time travel, the distance will decrease a little, given that the time array, tVec = 0:interval:100, where interval = 0.1, and velocity, vel = 0.1. Thanks.

start = [1 2];
endpos = [8 8];
interval = 0.1;
vel = 0.1;
tVec = 1:interval:100

What are the (x and y) components of the velocity? You have only stated a magnitude.

在 MATLAB Online 中打开

start = [1 2];
endpos = [8 8];
x = [start(1) endpos(1)]' ;
y = [start(2) endpos(2)]' ;
interval = 0.1;
vel = 0.1;
tVec = 1:interval:100 ; 
p = polyfit(x,y,1) ; 
xi = linspace(x(1),x(2),length(tVec)) ; 
yi = polyval(p,xi) ;
plot(x,y,'*r',xi,yi,'b')
