when i add 's' when writing a program for matrix in script then there is no space between the eelements of any row

fprintf('FIRST TYPE NUMBER OF ROWS AND COLUMNS\nTHEN TYPE THE VALUES OF THE ELEMENTS\nIN THE SEQUENCE OF\n(1,1),(1,2),...,(1,n),(2,1),(2,2),...,(2,n),...,(m,1),(m,2),...,(m,n)\nWHERE (r,c) MEANS THE ELEMENT OF\nrth ROW AND cth COLUMN.\n')
m=input('ENTER NUMBER OF ROWS    : ');
n=input('ENTER NUMBER OF COLUMNS : ');
for r=1:m
    for c=1:n
        MATRIX(r,c)=input('ENTER THE VALUE OF THE ELEMENT : ','s');
    end
end

Wrap input in str2double:

MATRIX(r,c) = str2double(input('...','s'));
