please use MATLAB AND GIVE THE CODE IN THE SOLUTION FOR IT$.$Q$1-$ Write a user$-$defined function that calculates grade point average $($GPA$)$ on a scale of $0$ to $4,$ where $A=4,A-=3\mathrm{.}7,B+=3\mathrm{.}3,B=3,B-=2\mathrm{.}7,C+=2\mathrm{.}3,C=2,C-=1\mathrm{.}7,D+=1\mathrm{.}3,D=1,$ and $E=0.$ For the function name and arguments, use av $=$ GPA$($g$,$h$).$ The input argument $g$ is a vector whose elements are the numerical values of the grades. The input argument $h$ is a vector with the corresponding credit hours. The output argument av is the calculated GPA. Use the function to calculate the GPA for a student with the following record:

$\backslash$table$[[$Grade$,A-,B,B+,C,E,A,D+,A$

please use MATLAB give the code DONOT use PYTHON.
