Is there something similar in functionality to the Curve Fitting Library for C#?

Question

C++ / C#

Matlab has a Curve Fitting Toolbox, is there something similar in functionality for C#? Mostly interested in the possibility of easy work with matrices and, of course, finding the coefficients of equations by the least squares method.
