[ROOT] fitting Data without the need to write them into a histogram

Hello!

I have a set of arrays with data which needed to be fitted to a user defined 
function. 
Up to now the prototype writes them into a TGraphErrors object and using the 
TGraphErrors::Fit() function the desired function is evaluated.

Is there a possibility to fit (TMatrixD, TArray..etc.) data without the need 
of defining a histogram, canvas or anything else which tend to make graphical 
output?
Thanks in advance.


Cheers,

Ralph
