**svd_basis_test**
is a MATLAB program which
calls svd_basis() to apply the singular value decomposition (SVD) to
a set of data vectors, to extract the leading "modes" of the data.

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

- svd_basis_test.m, calls all the tests.
- svd_basis_test.sh, runs all the tests.
- svd_basis_test.txt, the output file.

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.
