If you have any lines in the loop that do calculations and do not end in semi-colons, then add a semi-colon to the end of the line.

If you have any lines in the loop that use disp() or fprintf(), then comment those out.

I didn't know where to start, so look at this. I tried to preserve your code as much as possible

[edit]

clc;clear
number=1+round(rand*(9));
guess = 0;
total=0;
while guess~=number
      if(guess<1 || guess>10);
          disp('Invalid')
               % removed elseif case here based on Fangjun's comment
      else
          disp('incorrect, guess again');
      end
      total=total+1;
      guess = input('Enter a number between 1 and 10:');
  end
  fprintf('You guessed the correct number %g in %g attempts\n',guess,total);

MATLAB: How to get only the last value in a ‘while loop’

You haven’t posted your code, so I’m making an educated guess here.

Put a semicolon ‘;’ at the end of the statement that is displaying in the loop. That will suppress the display without affecting the functions in the loop.

At the end of the loop, the last value of the variable will be the value stored in the variable.
