Hello, I am new to matlab, and I am not sure how to use loops.
I am being asked to count the number of terms that keeps the equation k^2+2*k <100.
This is what I have, but all it is giving me is: count=1
count=0;
k=1:10;
while (k < 100)
k=k.^2+2*k;
count=count+1
end

k = 1 : 10;
loopCounter = 1;
while loopCounter < length(k)
theSum = k(loopCounter) .^ 2 + 2 * k(loopCounter)
if theSum >= 100
break; % Quit the loop
end
loopCounter=loopCounter+1
end
loopCounter % Show final value

k=1:10
is a vector.
while k<100
is a vector test equivalent to 10^2+2*10 = 120 and that is not less than 100 so the test is no longer true for all of the elements.
while all(k<100)
But after 1 step, the 10 component of k gets mapped to
