svd_basis_weight_test

svd_basis_weight_test, a FORTRAN90 code which calls svd_basis_weight(), which applies the singular value decomposition ("SVD") to a set of weighted data vectors, to extract the leading "modes" of the data.

svd_basis_weight, a FORTRAN90 code which is similar to SVD_basis, but which allows the user to assign weights to each data vector.

Source Code:

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

The user's input:

• 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.

There are two options for the weight files:

• weight_even.txt, even weights.
• weight_uneven.txt, weights of 0, 5, 1, 0.1, 0.2.

EXAMPLE 1 uses no averaging and even weights. The output data consists of 4 files, all of which are SVD basis vectors:

• ex01_input.txt, the input commands.
• ex01.txt, the output file.
• ex01_svd_001.txt, output SVD file #1.
• ex01_svd_002.txt, output SVD file #2.
• ex01_svd_003.txt, output SVD file #3.
• ex01_svd_004.txt, output SVD file #4.

EXAMPLE 2 uses no averaging and uneven weights. The output data consists of 4 files, all of which are SVD basis vectors:

• ex02_input.txt, the input commands.
• ex02.txt, the output file.
• ex02_svd_001.txt, output SVD file #1.
• ex02_svd_002.txt, output SVD file #2.
• ex02_svd_003.txt, output SVD file #3.
• ex02_svd_004.txt, output SVD file #4.

EXAMPLE 3 uses averaging and even weights. The output data consists of 5 files, all of which are SVD basis vectors:

• ex03_input.txt, the input commands.
• ex03.txt, the output file.
• ex03_svd_000.txt, output average vector.
• ex03_svd_001.txt, output SVD file #1.
• ex03_svd_002.txt, output SVD file #2.
• ex03_svd_003.txt, output SVD file #3.
• ex03_svd_004.txt, output SVD file #4.
