s1 = zeros(3,n);

for m=1:n

    q = input('sub= ','s');

If you want to create an array of mixed datatypes (e.g. numbers and strings), you'll need to use a cell array.

To do this, you would replace s1 = zeros(3,n) with:

s1 = cell(3,n);

Then you would need to reference the elements of this cell array using { } brackets instead of ( ) parentheses. So your code would look like this.

%input section
n = input('=');

% calculation section
s1 = cell(3,n);

for m = 1:n

      q = input('sub= ','s');
      d = input('hour = ');
      w = input('degree =');
      s1{1,m} = q;
      s1{2,m} = d;
      s1{3,m} = w;
  end

disp (s1)
