How to plot a function over a time interval in specific time increments?

xt = @(t) sin(pi*t);
>> fplot(xt,[0 20], 'MeshDensity',100)
>>

Gives me a plot of a function of time over a time interval; how would i plot in this function in specific time increments (time steps)?

Hi,

Here is the plain answer:

xt = @(t) sin(pi*t);
dt = pi/100;
t = 0:dt:20;
plot(t, xt(t))

How do i change the time increments?

change dt that is the time increment, e.g. in order to take 0.01 time step, dt = 0.01. That is all. Good luck.
