i =0;

while (i<10)

            i = i+1;
            x = input('enter the number');
            if isreal(x)
                if isinteger(x)
                end
            end
           if (x>255)
    disp('"error:Value too big."')

else if ((x>=0) && (x<=255))

       disp('<x>')
       else
        disp('-1')
    end
           end
end
What's wrong with this script? In command window, it appear the letter <x>. But I want to get the input number of x. Besides, it can only do it 10 times whatever the number I input. I expect it can work during the range 0-255 10 times. How to change it?

Shi, check out

 fileID = fopen('num.txt','w');
 while (i<10)
    x = input('enter the number: ');
    if isreal(x)                     % no action?
        if isinteger(x)              % no action?
        end
    end
    if (x>255)
        disp('"error:Value too big."');
    elseif ((x>=0) && (x<=255))
        disp(['<',num2str(x),'>']);  % display the value of x
        i = i+1;                     % increment i if x in range
        fprintf(fileID,'%d\n',x);
    else
        disp('-1');                  % display string '-1'
    end
 end
 fclose(fileID);
