Display Values That Satisfy a While Condition

Hi All,

I have a function that calculates and displays a matrix based on some input variables, this matrix has to be real and to contain zeros in some cells. So I use a while loop to iterate through possible values until I find the good ones. My code is a little long but looks like this:

function Z = myfunction(n,p)
check = 0;
while check == 0;
... % Generate a matrix
if isreal(S)    % Check whether matrix is real
    if ~all(S(:))    % Check whether matrix contains zeros
        check = 1;
    end
end
Z = S;

I would like to see the values for which my conditions are satisfied. How can I do that? I tried:

disp(v);

at the end of the function, but it's not working.

Thanks a lot in advance.

What is "v" in this context? Which "values" are you trying to display? Is screen output okay as it goes along, or does the information have to be returned back out of myfunction?

You might prefer the cleaner code

while true
  ... %generate the matrix
  if isreal(S) & any(S(:) ~= 0)
    break;   %leave the loop
  end
end
%we got here because of break
