MATLAB: Hello, how can I fix this function? I’m new to MATLAB

Question

I'm trying to create a code that allows me to input test grades and with that grade display a letter grade

function[MYCOURSEGRADE]=Problem(k)
y=input('Grade Value for Exam1:');
x=0.35*(y);
p=input('Grade Value for Exam2:');
s=0.4*(p);
R=input('Grade for Recitation Work:');
d=0.25*(R);
k=x+s+d;
disp('Total Grade Value is:');
disp(k)
if k>=90 && k<=100
    MYCOURSEGRADE='A';
elseif k>=86 && k<=89
    MYCOURSEGRADE='B+';
elseif k>=80 && k<=85
    MYCOURSEGRADE='B';
elseif k>=75 && k<=79
    MYCOURSEGRADE='C+';
elseif k>=65 && k<=74
    MYCOURSEGRADE='C';
elseif k>=55 && k<=64
    MYCOURSEGRADE='D';
elseif k<=54
    MYCOURSEGRADE='F';
disp(MYCOURSEGRADE)
end
end

Answer 1

Remove the second

function[MYCOURSEGRADE]=Problem(k)

Move the line

disp(MYCOURSEGRADE)

one line down, to after the 'end' you have there. Or remove that line, since you will be returning the grade from the function.
