I have tried to create Rosin-Rammler function for own use with my code
function q = rosinrammler(x, x50, n)
q = 1 – exp((-x/x50)^n);
However, when I input the value for example x = 2e-9, x50 = 100e-9 and n = 0.1 the output show me the complex number such as
q = rosinrammler(2e-9, 100e-9, 0.1)
q =
-0.861067915307539 – 0.394670349292600i
Where I think the result shoud be real number such as 0.491476239432908. This results I mannually calculate from 1 – exp(-0.02^0.1). I have found that the complex numer is generated when I try to power (-x/x50)^n.
So if anyone can help me, please I am very appreciate
Thank you
