Section 7.8 The while loop
MATLAB also has a
while loop whose syntax is given here:while expression % use when number of loop iterations
command % is not necessarily known
command
...
end
MATLAB can handle factorials of really large numbers quite easily. Here is code using a while loop that determines the first integer n whose factorial has at least 100 decimal places:
n = 1;
fact = 1;
while fact < 1e100
n = n + 1;
fact = fact * n;
end
fprintf('%d! = %g\n', n, fact)
Running this code yields:
70! = 1.19786e+100
There is no do-while loop as there is in C. So the only two types of loops are the
for loop and the while loop. Fewer choices to make!
