implement vector "shifting"
because I'm working with time series, I find that I am often getting rid of the first element of my vector, and adding a new element at the end.
To do so I write a loop to iterate through the vector.
I assume my way of doing this is relatively slow, and it would be much faster if it was a native method.1 vote -

Clone
Override .Clone for the various matrix storage classes. Right now it's in the generic class and calls .At a zillion times instead of just doing an array block copy.

Confirmed, managed dense matrix implementations are missing a proper override of CopyTo (some other implementations already do override it). Needs a github ticket.

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.

Histogram constructor with buckets. Data is applied to the buckets.
I need to create a histogram with buckets from another histogram and expect my data to be counted relative to those buckets.

Add Rotation Matrix and Vector classes for 2D, 3D and generic sized spaces
2D and 3D calculations could benefit from optimized functions for Rotation Matrices, 2D and 3D vectors, Solving for Transformation or Rotation Matrices, using Quaternions, and more.

add function generation for common functions
Add function generations for common functions including number of points, magnitude, and domain.
E.g.
SquareWaveSignalGeneration( Npoints, x1,x2, mag, offset, freq, etc)
GuassianSignalGeneration(...)
ErfSignalGeneration(...)
sineSignalGeneration(...)
TriangleSingalGeneration(...)

how to calculate eigenvectors?
I have this code to calculate eigenvalues/vectors, however, it causes some errors when compiled. How can I solve?
----------------------------------------
using MathNet.Numerics;
using MathNet.Numerics.LinearAlgebra;class Test
{
static void Main(string[] args)
{
Matrix m = new Matrix(new double[][] {
new double[] { 10.0, -18.0 },
new double[] { 6.0, -11.0 }});// alternative way to create the matrix:
// double[][] data = Matrix.CreateMatrixData(2, 2);
// data[0][0] = 10.0;
// data[1][0] = 6.0;
// data[0][1] = -18.0;
// data[1][1] = -11.0;
// Matrix m = new Matrix(data);EigenvalueDecomposition eigen = m.EigenvalueDecomposition;
Complex[] eigenValues = eigen.EigenValues;
// eigenvalues: 1, -2Matrix eigenVectors =… more

Implement a real number type that has a variable base. EG would be using binary, or hexadecimal, etc
Having support for variable bases can result in less computation. Maybe converting to binary or hex for faster computation then moving back? But the support for base variablility would help.

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.
