%description
The synchrosqueezed wavelet transform is implemented. The package is a
translation of MATLAB Synchrosqueezing Toolbox, version 1.1 originally
developed by Eugene Brevdo (2012). The C code for curve_ext was authored
by Jianfeng Lu, and translated to Fortran by Dongik Jang. Synchrosqueezing
is based on the papers: [1] Daubechies, I., Lu, J. and Wu, H. T. (2011)
Synchrosqueezed wavelet transforms: An empirical mode decomposition-like
tool. Applied and Computational Harmonic Analysis, 30. 243-261. [2]
