Defining a for loop

Just wondering some of the basics. How to I represent all possibilities of a variable?

I'm trying to say for every time t

How to I put that "for" part into a proper code format?

It depends on the range of your t variable and how finely you want to represent that.

If 0<=t<=1, then you can't represent it in a computer with an infinite number of values (continuously), but you can do:

t = 0:0.001:1;

represent it in increments of 0.001. Or

    t = linspace(0,1,1000);

For example:

    t = 0:0.001:1;
    x = sin(t);
    plot(t,x)

In a "vectorized" language like MATLAB, it is often better to represent things as vectors, or matrices when possible, and then evaluate things over that set, so your "for all t" becomes:

1.) define a vector of t values

2.) evaluate something over for all t in that set

 Matlab code
t0= 0; %assign an initial time t0
tf= 100; %set final time tf
for t=t0:tf
   {execute commands}
end

Is this all you're asking for?
