How do i create a simplified version of a continuous time unit step function?

For a class we have to create a simplified version of a continuos time unit step function as well as a pulse signal and a ramp signal this is what i have so far

 %%Continuous Time Step Function

function p=crwstep(t) % random name

p=unitstep(t);

end

For my pulse signal I have to use the step signal and this is what i have, which i think is correct(once i get the step signal down, %% Pulse Function

function p=crwpulse(t,m,n)

p=crwstep(t-n)-unitstep(t-m);

end

What am i doing wrong??

The following example shows how to create a variety of signals such as the unit impulse, unit step and unit ramp signals:
