Create a grid. trapz each column to get a row vector of areas for each column. trapz that row vector to get a single total area.

Use the str2func (link) function. I would also use vectorize (link):

fun = input('enter integrand = ', 's')

fun = str2func(['@(x,y) ' vectorize(fun)])

Q = integral2(fun, xmin, xmax, ymin, ymax)

MATLAB: Trying to create a GPA calculator

Hi Seong,

You can change your function to something like this:

function GPA = calculateGPA()
 %Output:GPA- Culmilative GPA
 Ask = input('How many classes are you taking?')
 numClass = Ask;
 totalEarned = 0;
 totalCredits = 0;
 for i =1:numClass
    TRANSCRIPT(i).CourseName = input('What is the Course Name?', 's' );
    TRANSCRIPT(i).CourseNumber =input('What ss the Course Number?', 's');
    TRANSCRIPT(i).CourseCredits = input('What is the Course Credits?');
    TRANSCRIPT(i).CourseGrade = input('What is your grade in that class?');
      totalEarned = totalEarned + (TRANSCRIPT(i).CourseCredits * TRANSCRIPT(i).CourseGrade);
      totalCredits = totalCredits + TRANSCRIPT(i).CourseCredits;
   end
   GPA = totalEarned/totalCredits;
  end

Hope this helps!
