Hi, how can I calculate a matrix by asking a user's input? For example, ask user to input a matrix such as [1 5 3] and change the middle number by adding the numbers next to it and take average, So in this case it would be [1 (1+5+3)/3 3] which will output [1 3 3]. Thank you.

This sounds like a homework question. Then please post, what you have tried so far and ask a specific question.

prompt = 'input a matrix such as [1 5 3]? ';
try
x = input(prompt);
if all(size(x) == [1 3])
x(2) = sum(x) / 3.0;
disp(['calculated result is [' num2str(x) ']']);
else
disp('size of input matrix is not 1 row by 3 columns.');
end
catch
disp('input style is not as a matrix!');
end
