SVD_SNOWFALL is a Python library which demonstrates the use of the Singular Value Decomposition (SVD) to analyze a set of historical snowfall data.
The snowfall data consists of records for the winters of 1890-1891 to 2016-2017, of the snowfall in inches, over the months from October to May, as measured at Michigan Tech.
This data can be regarded as an 8 by 127 matrix A. Applying the singular value decomposition produces the factors
A = U * S * V'and it is the purpose of this library to consider what these factors indicate about the snowfall data.

SVD_SNOWFALL is available in a C version and a C++ version and a FORTRAN90 version and a MATLAB version and a Python version.
FINGERPRINTS, a dataset directory which contains a few images of fingerprints.
TIME_SERIES, a dataset directory which contains examples of files describing time series.
