Fliping a value between zero and one

Asked by Rooy

When p=0;

I have to use a loop to flip the value of p between 0 and 1 and each time it has to be different in a single line of code.

Thank you


What does the "When p=0;" mean? You only have to flip when p=0???

When you say "flip the value of p between 0 and 1" does that mean that p is either 0 or 1 only, or does it mean p can have a value between 0 and 1, like p=.426973 and flipping means inverting like flipped_p = 1-p?

This was the question given : Write a MATLAB program that will start with the variable p=0. After the initial assignment to p, have a loop flip the value of p between 0 and 1, changing it once each loop iteration USING A SINGLE LINE OF CODE. [HINT: This is a math challenge.] Display it each iteration, using the pause() function to stop the loop temporarily each iteration

Thank you everyone for all the help

Is this what you're looking for?

for k = 1 : 5 % Here's the iterative loop it requested
	% Here's the single line
	p = ~p
fprintf('Done with demo!\n');


right !

Alternatively, if p should keep its type DOUBLE:

p = 1 - p;

That also works for any value or p in between 0 and 1, like I asked about in my comment way up at the top. So perhaps this is the most general solution.

 your_vector=mod(0:1000,2);  %  single line code
   for i=1:length(your_vector)
   %  YOUR CODE

 for i=1:N
  if mod(i,2)==0

Would you count this a one line of code ? Thank you
