Welcome to our official feedback forum. Do you have an idea? Do you recognize a good idea when you see one? We want to hear from you!

I suggest you ...

You've used all your votes and won't be able to post a new idea, but you can still search and comment on existing ideas.

There are two ways to get more votes:

  • When an admin closes an idea you've voted on, you'll get your votes back from that idea.
  • You can remove your votes from an open idea you support.
  • To see ideas you have already voted on, select the "My feedback" filter and select "My open ideas".

      • Add methods for linear and quadratic programming

        Linear and quadratic programming methods are great techniques for minimization problems. Other, more complicated methodologies - such as MPC - can built on top of them fairly easily.

        • Provide principle component analysis

          Extend the linear algebra part with PCA using either Singular Value Decomposition or Eigenvalue Decomposition. Easy implementation, great value!

            • Investigate Mono.Simd

              The upcoming Mono.Simd assembly is nearing release. Using these functions in certain areas could give massive performance gains.

                • Add support for surface interpolation (2D, mesh)

                  Extend the interpolation methods to support 2D surface interpolation, i.e. on a mesh. See http://community.opensourcedotnet.info/forums/t/565.aspx

                    • Add row echelon and reduced row echelon form computation

                      Computing reduced row echelon and row echelon form of a Matrix could be used with Gaussian and Gauss-Jordan elimination techniques.

                      • VSLab

                        I think this is a great project. I am suggesting your library for VSLab (http://www.codeplex.com/vslab). I think that an F# wrapper would be great. Are you interested in contribute with your math library in creating a Matlab like environment? Have a look to the project!

                              This a proposition to add a Moore-Penrose pseudoinverse implementation (couldn't find it in Math.net numerics). This example is implemented as a Extension Method to the Matrix<double> class. The pseudoinverse it is computed using the singular value decomposition. The algorithm comes from Wikipedia.

                                • Add stochastic processes

                                  Almost all modern financial analysis are built around stochastic processes. There are many processes, some general like time series and some more specific. It would be very useful for people working in the finance field.

                                  • Add support for cuda

                                    Is this possible to split the matrix multiplication algorithms to use processor and gpgpu all at the same time?

                                    It would be an amazing feature to be added.

                                    • Allow interpolation over complex numbers

                                      Currently interpolation only supports real numbers. Consider also to provide special schemes like Laurent interpolation around the unit circle.
