These are M-file examples related to the Erlang B formula for blocking probablity in telecommunications networks. They have been tested using MATLAB 5.3.1.29215a R11.1 but they are so simple they would probably work with any version.

I was trying to understand the code because I am working in a code that let come with the same result as this paper:
ITU-R M.1768-1 called Methodology for calculation of spectrum requirement IMT. I have this report many times and other article trying to find out the equation and relation between the user density, session arrival rate, mean service bit rate, average session duration?

I read the code and the description, but this model only use the session arrival rate and he average session duration, Has anyone know how to calculate the spectrum capacity for switch circuit and switch package communication, or anyone know which equation use these: the user density, session arrival rate, mean service bit rate, average session duration to estimate the spectrum capacity?

thanks

This routine uses an oversimplistic algorithm that can fail in some cases. e.g.

>> erlangb(1000,900)

ans =

NaN

The correct value is 5.9-05
