Explanation / Answer

With loop control statements, you can repeatedly execute a block of code. There are two types of loops:

for statements loop a specific number of times, and keep track of each iteration with an incrementing index variable.

For example, preallocate a 10-element vector, and calculate five values:

while statements loop as long as a condition remains true.

For example, find the first integer n for which factorial(n) is a 100-digit number:

Each loop requires the end keyword.

It is a good idea to indent the loops for readability, especially when they are nested (that is, when one loop contains another loop):

You can programmatically exit a loop using a break statement, or skip to the next iteration of a loop using a continue statement. For example, count the number of lines in the help for the magic function (that is, all comment lines until a blank line):
