where kin$(1,2,3,$dotsN$)$ is the number of a particular course in the list, $G{P}_{k}in[0\mathrm{.}0,4\mathrm{.}0]$ is the grade point earned in course #k$,$ and $C{H}_k$ is the number of credit hours for course ${?}^{\text{'}}k.$

Write a code to calculate the GPA for you by creating arrays GP and $CH,$ then using built$-$in MATLAB functions and array operations to calculate your GPA. Use the variable names GP$,$ CH$,$ and GPA.

Your code should display nothing to the screen except a short message $($such as$,$ "Your GPA is$")$ and the GPA itself.

Note: You should choose the number of courses, the number of credit hours for each, and the grades in each. For privacy reasons, I do not recommend you use your own grades, though it is up to you.
