How can I repeat the code for multiple timesteps?
显示 更早的评论
Hi, I need to write a code to let a particle move multiple timesteps, where the timesteps can be any number (e.g. 2 or 50). The situation is the following, I have an array where a x-coordinate, an y-coordinate and the direction are in:
Q =
1 2 1
1 3 1
3 3 2
3 1 1
2 3 2
To make it easy, x and y can be 1, 2 or 3 and the direction can be 1 or 2. The direction I have defined as:
if Direction == 1 %If the direction ==1 then x stays equal but y becomes 1 higher
x = x
y = y + 1
end
if Direction == 2 %If the direction ==2 then y stays equal but x becomes 1 higher
x = x + 1
y = y
end
But how can i let this repeat for multiple time steps, because, like the code above is now, this should happen in one timestep where this timestep (dt) is set.

for stepnum = 1 : 100
.... your existing lines
end

It is a for loop. for acts like a repeated assignment statement.
You can use whatever variable name is convenient for your purposes. For example,
for timestep_number = 1 : 100
... your existing lines
end
You could also use
for time = 0 : 0.01 : 5
.... your existing lines
end
but in practice it is usually easier to iterate over step numbers than to iterate over times if you need to record data as you go along.
