FALCON is a library and a program to quickly calculate a large variety of currently 87 measures of complex networks. An example are directional, unweighted cluster coefficients of all nodes of the network. It is highly optimised for fast and parallel calculations on standard desktop computer hardware. Most intensive calculations can be done on GPU (graphics card). Since FALCON was developed for neuroscientific networks it focuses on memory-intensive adjacency matrices. For sparse networks alternative space-saving CSR graphs can be used.
