Matlab code for #$3!$ Please.

Thermal Systems Ilc is a consulting company and they do work in the area of heat engines and refrigeration systems. After passing the go$/$no$-$go check, they have asked you to provide them with a portfolio that shows your knowledge and skills in thermal systems and in particular: thermodynamics cycles, coding, use of XSteam, CoolProp and other software tools.

Please provide a portfolio with diagrams of typical refrigeration and power cycles, including:

$1.$ A $\backslash ($ P$-$h $\backslash )$ and a $\backslash ($ T$-$s $\backslash )$ diagram of a vapor$-$compression refrigeration cycle

$2.$ A $\backslash ($ P$-$v $\backslash )$ and a $\backslash ($ T$-$s $\backslash )$ diagram of a Rankine cycle with superheat

$3.$ A $\backslash ($ P$-$v $\backslash )$ and a $\backslash ($ T$-$s $\backslash )$ diagram of a Brayton cycle $($in a jet engine application$)$
