Write an anonymous MATLAB function GPA that calculates grade point average on a scale of 0 to 5, where A = 5, B = 4, C = 3, D = 2, and F = 0. Arguments to the function are G, a string whose elements are letter grades, and C, a vector with corresponding credit hours. Output is the grade point average rounded to the nearest tenth. Use the function to calculate the average of a student whose record is: Grade ABFCBADA Credit Hours 4 3 3 3 23433
