Tasks: Done And To Do

This page aims to be a handy reference not only of the work done but also of work pending for the next planned release. Users who want new features should submit patches to this page in the unclassified section of this document. Developers who want to lend a hand can grab tasks from this page. Everyone can see the progress which is being made.

The following is a list of items still TODO for Math. Contributions are welcome!

Many of these will always be a required. Please focus on applying format standards and provide as many test cases as possible for your code.

Develop user's guide following the package structure.
Incomplete Sections: 6.2 Double Array Utilities, 6.4 Binomial Coefficients, 7.4 Complex Formatting
Performance and accuracy testing.
If anyone is interested in helping out here, what we could really use is a wider selection of test cases for the core numerical functions and validation against either other packages (e.g. R for the statistical stuff), verified datasets, or experiments comparing implementions using floats to doubles.
Test Coverage.
Clover tests show gaps in test path coverage. Get all tests to 100% coverage. Also improve test data and boundary conditions coverage.
Code review.

Code review is a continuous process that all Contributors and Developers should practice while working on the code base.

  • Javadoc generation is still throwing warnings. Bring the Javadoc into compliance (i.e. reach zero warnings).
  • Verify that the code matches the documentation and identify obvious inefficiencies or numerical problems. All feedback/suggestions for improvement/patches are welcome.
  • CheckStyle with modified properties still shows many errors. Try to clean these up.
Javadoc
Bring all javadoc up to requirements in the Developer's Guide
Run linkcheck and fix all broken links in Javadoc

These current tasks are planned and need completion for the inital release

Root Finding
  • Rework unit tests for root finding
  • CheckStyle with modified properties still shows many errors. Try to clean these up.
  • Finalize API (maybe move to stateless implementation)
Complex Number Library
An initial submission of a complex number library has been donated by Brent Worden. It has been added and is open to be reviewed/tested by others for feedback. The implementation is based on the following source: http://myweb.lmu.edu/dmsmith/ZMLIB.pdf.
RealMatrix
  • Implement rank() method or drop from interface.
BeanList Statistics
  • Refactor BeanList statistics, find appropriate package placement
Statistics
  • More inference methods
  • Multiple regression
Linear Algebra
  • More matrix decompositions (Cholesky, QR, SVD) and framework to support.
  • Sparse matrices
