File Information

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

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

>> erlangb(1000,900)

ans =


The correct value is 5.9-05
