recursive function with 2 variables doesnt work

Hi there,

i try to get a recursive function

and for

for exampble:

i tried this function:

function x = s(p,t)
if t==1
    x = p;
else
    x = p*s(p,t-1)+(1-p)*(1-s(p,t-1));
end
end

but when i try to call it with

>> x = s(0.75,2)

i would expect something like

x = 0.625

but i get the error

Index in position 2 exceeds array bounds (must not exceed 1).

so i thought maybe i dont need the p in the function. So i tried:

function x = s(t) etc.

and it works for t=1. But when i call the function with

>> x = s(2)
Index exceeds the number of array elements (1).

What am i doing wrong?

For me, your function works as expected.

Maybe you accidentally also created a variable s in your workspace, and you are trying to access that instead of the function? What do you get from

which -all s

Hey thanks for your answer!

>> which -all s
s is a variable.

you where absolutly right! I deleted the variable und now it works!

Thank you very much!
