$(1)$ Write a comment at the start of the code to describe the code adding $\%$symbol$\%$ code to generate transfer function for task $1(2)$ You can input the numerator and denominators of the transfer function asmatrix.$(3)$ Let$$s call $$num$1$ as numerator matrix, $$den$1$ as denominator matrix of thetransfer function G$1($s$).(4)$ Denominator of G$1($s$)$ is a second order equation s$2+2$ s $+10.$ This equationcan be considered to have three terms s$2,$ s$1$ and s$0$ with $1,2$ and $10$ ascoefficient. Thus, we can define the denominator variable of transfer functionG$1($s$)$ as:den$1=[1210]$;$(5)$ Since there are no s$2,$ s$1$ terms in the numerator we write their coefficients as$0$ and $0.$ Thus, we can define the numerator variable of transfer function G$1($s$)$as:num$1=[0010]$;$(6)$ Write the above two variables in your code.$(7)$ You can now call the following transfer function in to generate the transferfunction:G$1=$tf $($num$1,$ den$1)$;$(8)$ You can check by printing you have got the right transfer function for G$1($s$)$ byinserting theprintsys $($num$1,$den$1)$;$(9)$ Double check you are in the same directory in which your $$m$$ script exist.$(10)$ Now click the editor section of MATLAB and then click $$RUN$$ button in thetop to execute or run the code and get the result.$(11)$ Check your command window shows the transfer function with same valuesas in G$1($s$)$ transfer function.$(12)$ Now repeat the above steps to create code for the transfer function G$2($s$).$Use:num$2=[05]$;den$2=[15]$;$(13)$ Now click the editor section of MATLAB and then Click $$RUN$$ to check youget the right G$2$ transfer function$(14)$ Finally, create the cascade transfer function by calling the following function.$[$num$,$ den$]=$series $($num$1,$ den$1,$ num$2,$den$2)$;$(15)$ Print the cascade transfer function using the following print function;printsys $($num$,$ den$)$;$4$

$(16)$ Now click the editor section of MATLAB and then Click $$RUN$$ to check youget the transfer function for the cascade system.$(17)$ Repeat the step $(14)$ & $(15)$ to create the parallel transfer function of task $2$:$[$num$,$ den$]=$parallel $($num$1,$ den$1,$ num$2,$den$2)$;printsys $($num$,$ den$)$;$(18)$ Now click the editor section of MATLAB and then Click $$RUN$$ to check youget the transfer function for the parallel system.$(19)$ Repeat the step $(14)$ & $(15)$ to create the closed loop transfer function of task$3$:$[$num$,$ den$]=$feedback $($num$1,$ den$1,$ num$2,$den$2)$;printsys $($num$,$ den$)$;$(20)$ Now click the editor section of MATLAB and then Click $$RUN$$ to check youget the right G$2$ transfer function$(21)$ Use the step response command for the transfer functions obtained for thecascade, parallel and closed loop systems to obtain their step input response.sys $=$ tf$($num$,$ den$)$;step$($
