DWTCT (libdwtct) is a C library (implemented in C++) that provides the core transforms needed to compute floating-point wavelet transforms. This library aims to provide fast, lightweight and flexible functions on which other libraries or code (in any language with C-call capabilities) can build higher level transforms.

The library is compiled with OpenMP as default. An input parameter tells the library whether to use the parallel threaded code or not, and the number of threads to use can be set with a function call. See dwtct.h for the API.

From the top directory execute make and sudo make install.

A test program can be compiled with make testprog and run with make runtest.

Run make in the doc directory to generate the documentation.
