I need to create a function through switch statements that are from one bound to the next bound. How would i use the case to display bound1 through bound2. Every variable falling within the bounds is included in the case.

i have

switch n

case {bound1 through bound2}

Don't do that. Use logical indexing instead.

This is what I have so far

function [lettergrade] = curvedGrade(grade,bound)
a = (bound(1):100);
b = (bound(2):bound(1));
c = (bound(3):bound(2));
d = (bound(4):bound(3));
switch grade
    case{a}
        lettergrade = 'A';
    case{b}
        lettergrade = 'B';
    case{c}
        lettergrade = 'C';
    case{d}
        lettergrade = 'D';
    otherwise
        lettergrade = 'F';

No, do it like this:

[lettergrade] = curvedGrade(71,[90,80,70,60, 50])
lettergrade = "C"
function [lettergrade] = curvedGrade(grade,bound)
 gradeList=flip(["A" "B" "C" "D" "F"]);
 idx=discretize(grade,[flip(bound(:));100]);
 
 lettergrade=gradeList(idx);
 
end
