Homework Help: Unit step

  1. Sep 26, 2007 #1
    How do you represent a unit step in matlab as ONE function, y , for example. I know only how to graph multiple vectors on top of the same graph (using hold on/off) and getting the graph output, but i can't represent it as a function itself.

    Any ideas?

    If I understood your question correctly, you can do

    y = (t>=0)

    *Note : You have to predefine the vector t.

    for the unit step function y = u(t)

    Or use heaviside function.
