Incorrect number or types of inputs or outputs for function 'step'

Answer 1

Hi Archit,

It would be much easier to help if you copy/paste the actual code into the Question rather than a large screen capture.

In any case, even though that usage of step is obsolete it should still work as shown below.

num = 1; den = [1 2*.7*1 1];
t = 0:.01:1;
y = step(num,den,t);
which -all step(num,den,t)

/MATLAB/toolbox/control/ctrlobsolete/step.m

What result do you get if you run the code shown above with the num, den, and t as defined above?

What result do you get from just the 'which' command with your specific values of num, den, and t ?
