There is an issue trying to use the stblcdf on a matrix of points, some of the lines of code use 'any' which returns a vector. The result a silent returning some entries to be zero.

Thanks a lot for the code. It's been really helpful for my research. For stbfit, is it possible to specify some of the 4 parameters and only fit the rest?

best regards.

Great code!!, It helped me a lot to understand stable distributions, Thanks.

Do you have by chance any library for LFSN?

Simple to use, seems to do the job.

Fixed a bug where any() was misused in stblpdf, stblcdf and stblinv.
