Error using input Cannot call INPUT from EVALC.

After running the code the correct output is shown in the command window. However, when I try to publish as PDF this error occurs:

Error using input

Cannot call INPUT from EVALC.

Error in LLAB002 (line 48)

numericGrade = input('Enter Numeric Grade(0 to 100): ');

Here is my code

numericGrade = input('Enter Numeric Grade(0 to 100): ');

characterGrade = getCharacterGrade(numericGrade);

fprintf('Grade in Character: %c\n', characterGrade);

function characterGrade = getCharacterGrade(numericGrade)
    if numericGrade>=90 && numericGrade<=100
        characterGrade = 'A';
    
    elseif numericGrade>=80 && numericGrade<90
        characterGrade = 'B';
    
    elseif numericGrade>=70 && numericGrade<80
        characterGrade = 'C';
    
    elseif numericGrade>=60 && numericGrade<70
        characterGrade = 'D';
    
    else
        characterGrade = 'F';
    end
end

This is a limitation of the technology used to publish().

In order to get around it, you would have to have a function named input on your MATLAB path that displayed the prompt and then returned a fixed value instead of asking the user for the value.

You should consider making a function that takes the numeric grade as input instead.
