Matlab error: input argument not defined -

i wrote function as:

function f = factorial(x)  f = prod(1:x); f =factorial(5); end

but when tried running it, says input argument not defined. what's wrong this?

you have defined function recurses endlessly.

f = factorial(5);

in third line call function again, again call function once reaches third line, again call function... never done.

when implementing recursive solution need provide base case. here's example calculating factorials.

function f = factorial(x)     if x == 0 % base case         f = 1;     else         f = x*factorial(x-1); % recursive case     end end

example:

>> factorial(5)        ans =    120

as your

input argument not defined

problem, need tell used input argument. above example, any* integer x>=0 should work.

*as long f has enough bytes hold result.
