Is there a unit step function in MATLAB?

H = heaviside( x ) evaluates the Heaviside step function (also known as the unit step function) at x . The Heaviside function is a discontinuous function that returns 0 for x < 0 , 1/2 for x = 0 , and 1 for x > 0 .

What is a unit step response?

The response of a system (with all initial conditions equal to zero at t=0^-, i.e., a zero state response) to the unit step input is called the unit step response. If the problem you are trying to solve also has initial conditions you need to include a zero input response in order to obtain the complete response.

How do you find the step response in MATLAB?

y = step( sys , t ) returns the step response of a dynamic system model sys at the times specified in the vector t . This syntax does not draw a plot. [ y , tOut ] = step( sys ) also returns a vector of times tOut corresponding to the responses in y .
