expsum

Approximate a function by exponential sum

Description

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.
