Class TGo4FitModelGaussN

class TGo4FitModelGaussN

derived from TGo4FitModel

N-dimensional gaussian peak.

Has following parameters:
"Ampl" - amplitude;
"Pos0", "Pos1", ... - line positions;
"Width0", "Width1", "... - line widths;
"Cov0_1", "Cov0_2", ..., "Cov1_2", "Cov1_3", ... - covariations parameters.
To create instance of this model:

TGo4FitModelGaussN *g = new TGo4FitModelGaussN("Gauss", 2);

where first parameter - name of model component, second - number of dimensions.
