Detailed Description

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.
