SO I need to have a vector of random values (between -10 and 10) then replace the negative integers with another random number (using a while loop I assume) until all the numbers are positive. After all that is done I need to count the number of times it took before all the numbers became positive ( I will probably use count to do this) This is a suggested homework question that I have been stuck on for 2 weeks and I can tell that something similar is going to be on the exam next week.
Here is what I have so far.
a=-10; % min value
b=10; % max value
v = randi([-10,10],1,20) % generates Vector with 20 random integers
R = randi([-10,10],1,20) % Another random array to replace values
for n=1:10 % How can I use a while loop in this case?
idx = v < 0 % Am I doing the indexing right?
v(idx) = R(idx) %finally How can I make the count?
end
