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.

Int_t TGo4FitModelGaussN::GetAxisForIndex ( Int_t indx ) [inline]

Gets axis number (0 - x-axis, 1 - y-axis) for specified dimension of gaussian. Can be, that first dimension of gaussian assign to z-axis, 2-nd dimension to x-axis, 3-rd dimension to y-axis. Default (created in constructor) is normal numbering, when number of dimension is equal to number of axis.
