operates on matrices of complex numbers.

Polar shapelet decomposition uses matrices of complex numbers. Since Java 1.4 does not have a complex data type, we need a package for linear algebra working with the Complex elements.

We use the Complex class from the colt package.

For linear algebra algorithms we based the algorithms on relevant parts of the Jama package. All algorithms were rewritten using operations on Complex variables. The resulting package was tested using the matrix test class, also rewritten to work with Complex variables.
