Approximate a function by exponential sum
You need a newer C++ compiler that supports the C++11 standard, such as GCC (>= 4.8.0) and Clang (>= 3.2).
This library also depends on the following external libraries:
- Armadillo: C++ linear algebra library
- BLAS, LAPACK, or optimized BLAS/LAPACK libraries such as Intel(R) MKL, OpenBLAS, Apple Accelerate Framework etc.
- FFTW3
expsum is a header only library. You can use it by including header files
under include directory.
To build the program using expsum, you must link armadillo, blas lapack and
fftw libraries.
See, example program in example directory.
