Hello everyone, I need to create a for loop which iterates until it is met a specific condition, which in my case is the output being equal to a certain value. I know a while loop would suffice, though I would require a for-loop in order to use the index of the iteration to store the output of said iteration into an array, so that I can have a full accountability of all the results the loop gets.

for K = 1 : inf
do some calculation
stored_results(K) = the_output
if the_output == the_certain_value
break;
end
end
or
K = 0;
while true
do some calculations
K = K + 1;
stored_results(K) = the_output;
if the_output == the_certain_value
break;
end
end
However... remember that the == operator is looking for bit-for-bit equality, and it is possible that you cannot get bit-for-bit equality due to round-off and finite precision . You are typically better off checking to see whether the output is "close enough" to the desired value, such as with ismembertol()
