See if this works for you:

name=input('Enter your name:','s');

From the documentation for input:

str = input(prompt,'s') returns the entered text as a string, without evaluating the input as an expression.

MATLAB: How to handle errors

By default, input interprets the user input as a matlab expression and evaluates it. If the user input is not a valid matlab expression then it returns an error.

If you want the user to be able to enter something that is not a matlab expression, then you need to pass the 's' option to input:

kbinput = input(' ', 's'); %and please use a prompt rather than an empty string

All input (including numbers) is then interpreted as text. If on the next line you meant to test that kbinput is char (instead of the undefined variable next), then the test will always return true. If you want to make sure that the input is truly a number:

kbinput = input(' ', 's');
numericvalue = str2double(kbinput);
if isnan(numericvalue)
    error('you did not enter a number');
end

sizegroup=input('Enter number of students: ');
for k = 1:sizegroup
    name=input('enter name: ', 's'); %read in name and score
    score = input ('enter score: ');
    name_score{k,1} = name;          %save to cell array  
    name_score{k,2} = score;
end
disp(name_score)
