Hello, I'm solving a problem of probability and need to calculate a factorial(365), but the factorial function in Matlab gives me a result of Inf. Can anyone know how to use the factorial function to calculate a large number such as factorial(365),factorial(321) ? Thank you! Ben

You could use one of these FEX submissions by John D'Errico:

Also, consider reformulating your calculation to avoid these large numbers. E.g., I am guessing that this large factorial is part of an expression that has other large factorials as well. Look for ways to "cancel" portions of the calculation so that smaller calculations remain.
