use of hyperbolic function coth(x) inside a programming loop

[RogeliodelasCas]

i have been trying to use coth(x) inside a programming loop and i have an error saying "this function refers to itself inconsistently"

but, when i change the coth(x) just for x, the loop runs ok.

Please, see pdf file with the loop attached.

regards,

Please, disregard this question.

i found the problem.

i had problems with the units that i was using in the loop.

it is now working fine.

thanks anyways.
