Hello community,

x=7;
  while 7<=x<=10
  for i=lenght(z)
  for j=lenght(y)
    Calculate equation A and eq. B, depend y and z
    if t<0.5 && k<0.5
    Put New values for eq. A and eq. B
    break 
    end
    end
    end
x=x+1
    end

For example, at 1st step x=7, I will calculate 2 values and when they fulfill the conditions, I would like to save the new values and go to x=8 step. Can I see the results at the end (when the all loops are finished) like : x=7 t=0.4, k=0.3 A=27 B=13 x=8... x=9... x=10...

I hope it is clear, if it is not, please inform me to explain more. Thanks in advance!

This demo might be useful, for you:

count = 0 ;   % initialize a count 
iwant = zeros([],2) ;   % initialize the required out put 
while count ~= 10     % a while loop 
    x = rand ; y = rand ;   % some values 
    if x < 0.5 && y < 0.5    % a condition to save the result x, y 
        count = count+1 ;    % increment the count 
        iwant(count,:) = [x y] ;   % store values 
    end
end
