for loop with factorial as an increment

3 visualizzazioni (ultimi 30 giorni)
When you increment a for loop by factorial(n) is matlab updating n within the factorial or is it simply calculating the factorial value and using that as an increment.
ex.
does
factorial(1):factorial(2):factorial(n)
go 1 3 5 7 9 11....n since factorial(2)=2*1
or 1! 3! 5! 7! 9! 11!.....n!
I would test this myself but I do not have software at my disposal.

The moment factorial is evaluated, MATLAB just treats it like a number. Which means it would be your first option.

You can simply do:
loopvar = factorial(1:n)
for i = loopvar
% do something
end
loopvar will have the vector of factorials. In MATLAB you can simple use this variable in the loop as above

so if I wanted those to be incremented by two would loopvar=factorial(1:2:n) be correct?
