Matlab function plotting. A continuous step function

[Atlas3]

i could use a bit of tutelage with Matlab. I have a rather simple equation I would like to plot. I want to create a rational series of primes divided by their corresponding W value from the equation I have. P are primes 2,3,5,7,11,13... I am still working on this. Thanks

None of what you posted makes much sense, from what I can see.
What is a "rational series of primes divided by their corresponding W value"?

The first few lines of what you posted are:
$P = \frac a {(2, 3, \dots, a - 1)} \ne 0$ What does this mean?
$p(x) = (2, 3, 5, 7, 11) \in P, (1, 5)$ I have no idea what this means, either.
$a_0 = 0, ~a_1 = 1, ~a_2 = 2, \dots, a_{n + 1}$ Not enough information to figure out what $a_{n + 1}$ is supposed to be.
$w_0 = 0$
$w_1 = w_0 + a_1 = 1$
You lost me on $w_2$, and things really go downhill from there.
