Representing Unit Step Function in MATLAB

[DefaultName]

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.
