svd_basis, a Fortran90 code which applies the Singular Value Decomposition (SVD) to a collection of data vectors, extracting dominant modes;

Source Code:

• svd_basis_test.sh, runs all the tests.
• svd_basis_test.txt, the output file.

• input.txt, five lines of input that define a run.

The input data consists of 5 files:

• data01.txt, input data file #1.
• data02.txt, input data file #2.
• data03.txt, input data file #3.
• data04.txt, input data file #4.
• data05.txt, input data file #5.

The output data consists of 4 files, the first containing the average, and the next three containing the SVD basis vectors:

• svd_000.txt, output SVD file #0 (contains the average, which was requested by the user in the input file.).
• svd_001.txt, output SVD file #1.
• svd_002.txt, output SVD file #2.
• svd_003.txt, output SVD file #3.
