I'm trying to use function [LaypExpnt]=lyaprosen(y,dt)8 var from the https://ideas.repec.org/c/boc/bocode/t741502.html
it has function fnn that causes: fnn Unrecognized function or variable 'fnn
I cannot find ANY reference to fnn in Matlab HELP, but it seems to be legitimate (not a typo...)
can anyhone help me understand this?
THANK YOU

Could you please provide the code in which you are using "lyaprosen" function, so that we can investigate the case further?

The code for function fnn starts from line 228 of the file you indicated.
The code appears to work when I test in R2023b -- provided, that is, that the signal is more than 250 entries (larger if the provided dt is small enough.)
