svd_basis_test

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.

Source Code:

• 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.
