This is the Fortran source code in the Julia package FuzzifiED intended for exact diagonalisation (ED) calculations on fuzzy sphere.

The code can be compiled by make. Three options are required :

• LIB_DIR : the directory of the product libraries, . by default ;
• DLEXT : the extension of the shared library on the target system, so for Linux (by default), dll for Windows, and dylib for macOS ;
• NBITS : the number of bits of the target architecture, 64 (by default) or 32.

This package is developed by Zheng Zhou (周正) and contributors. If you have any questions, please contact physics@zhengzhou.page.
