How do you find the MTLAB code

What is the code for the following problem; Consider a closed-loop system that has the loop transfer function L(s) = Gc(s)G(s) = Ke-TS / s

a. Determine the gain K so that the phase margin is 60 degrees when T = 0.2.

b. Plot the phase margin versus the time delay T for K as in part (a).

This sounds like a homework assignment. If it is, show us the code you've written to try to solve the problem and ask a specific question about where you're having difficulty and we may be able to provide some guidance.

If you aren't sure where to start because you're not familiar with how to write MATLAB code, I suggest you start with the free MATLAB Onramp tutorial to quickly learn the essentials of MATLAB.

If you aren't sure where to start because you're not familiar with the mathematics you'll need to solve the problem, I recommend asking your professor and/or teaching assistant for help.

See the documentation for tf and bode. Try setting up and plotting your transfer function. Ask questions if you have further problems.
