可以使用math.net制作超过2维的矩阵

Question

I need to use a 4 dimensional matrix.

I am using math.net numeric library for c#,

I have tried the

Matrix<Matrix<double>> test;

but it didn't work

i know that I can write the following

Matrix<double> [][] test;

but I don't want it this way

Answer 1

No. The Math.NET Numerics Linear Algebra functionality operates on vectors and matrices, not on arbitrary-dimensional arrays (by design; other than libraries like ILNumerics which do operate on such arrays). As such it does not provide a 4 dimensional "matrix"-like data structure.

Do you really need tensor-arithmetics on top of that, or is this more about storing a table of matrices (or a cube of vectors)?
