Lib is a subsystem that contains a library of general purpose routines suitable for engineering type applications. It comprises modules for graphics (2D, 3D, timeseries), complex numbers, vectors, matrices, eigensystems, integration, root finding, special functions, random variates, linked lists, sorting, factorisation, timing, large sets, and an extended formatter.
This version of Lib contains many years of development since the last version was published, and some interfaces will have changed. It should be easy to adapt client code. Any issues could be discusson at http://community.blackboxframework.org/viewforum.php?f=38.
