hi,
i need to plot my corrdinates vs time. and my time to run with a loop function repeatedly. is there any other method for me to try without loop or any command options?

Hi Shane,
I am assuming that you have an array of coordinates to be plotted again a time vector, but without a loop.
The given workaround works for 100 points generated using sin function:
% Example data
time = 0:0.1:10;
coordinates = sin(time); % Example coordinate data array
% Plotting without a loop
figure;
plot(time, coordinates);
xlabel('Time');
ylabel('Coordinates');

Hi @shane
Generally, coordinates can be specified in 2D (planar) or 3D (spatial) formats. If you wish to plot the spatial coordinates against the time vector, resulting in a 4D problem, this can be challenging to conceptualize according to conventional practices. However, if your goal is to visualize the spatial trajectory of the particle over a time interval, you may consider using a parametric plot approach.
Here is my visualization of a particle moving along a spiral path as it approaches the event horizon of a black hole. This representation may be incorrect, as the spiral motion may not stick to the exponential decay law.
syms t
xt = exp(-t/10).*sin(5*t);
yt = exp(-t/10).*cos(5*t);
zt = -t;
fplot3(xt, yt, zt, [0 30])
xlabel('X'), ylabel('Y'), zlabel('Z')
