A C++ header-only library for evolving states under the Schrödinger equation using first-order Suzuki-Trotter and computing switching functions.

Installation

Suzuki-Trotter-Evolver can be installed as follows:

git clone https://github.com/Christopher-K-Long/Suzuki-Trotter-Evolver
cd Suzuki-Trotter-Evolver
cmake -S . -B build -DCMAKE_BUILD_TYPE=Release # set optional flags here
sudo cmake --build build --config Release --target install -j $(nproc)

There are several optional flags that can be set:

-DSuzuki-Trotter-Evolver_INSTALL_LIBRARY=ON/OFF(Suzuki-Trotter-Evolver is installed if set to ON)
-DSuzuki-Trotter-Evolver_BUILD_TESTING=ON/OFF (The unit tests and examples are build and run if set to ON)
-DSuzuki-Trotter-Evolver_BUILD_DOCS=ON/OFF (The documentation is build if set to ON)

These optional flags should be appended to cmake -S ../.. -B build. All three default to ON if the project is top level (i.e. if the project is not being build as a dependency of another project).
