  'digHolo' is a numerical library for processing batches of input off-axis
digital holography interferograms and outputting the corresponding
reconstructed fields. Optionally the library can perform a modal decomposition
of the reconstructed fields and is particularly efficient at Hermite-Gaussian
and Laguerre-Gaussian decomposition.
  The library is written in C++11 for the x86-64 (AVX2) architecture and is
intended for use primarily as a dynamic linked library (Windows) or shared
object (Linux) which the user can integrate into their own software. The
library can be compiled as an executable for processing interferograms from
disk using the command line. The library has dependencies on two external
libraries; FFTW and BLAS/LAPACK (functions cgemv, cgemm, cgesvd, sgels), but a
precompiled statically linked DLL is provided for Windows.
  A video tutorial is provided explaining usage of the software in addition to
this user guide. Coding examples for use in Matlab, Python and C++ are
supplied.
