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 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.

AddSubMatrix
For FEM analysis the AddMatrix method is very useful. In opposite to SetMatrix this method summarize elements.

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.

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!

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

Dense and sparse matrix slicing based on input user defined indices
This should allow functionality similar to MATLAB:
Suppose that A is the following matrixA = [ 10 20 30 40 ;
11 21 31 41;
12 22 32 42;
13 23 33 43]and I = { 1, 2, 4 } and J = { 3, 4 }
A_IJ = A[I, J]
should return a slice of the matrix according to the indices specified:
A_IJ = [ 30 40;31 41;
33 43 ]The same idea is very useful for arrays and it should work in both directions, for example:
A[I, J] += some3by2matrix;
The same…

Not in mainline but in one of the forks – to be merged back into mainline once ready
 Don't see your idea?
