## Detailed Description

Example describing how to use the different cumulative distribution functions in ROOT.

The macro shows four of them with respect to their two variables. In order to run the macro type:

root [0] .x mathcoreCDF.C
#include "TSystem.h"
#include "TF2.h"
#include "TCanvas.h"
void mathcoreCDF(){
TF2 *f1a = new TF2("f1a","ROOT::Math::breitwigner_cdf_c(x, y)",-10,10,0,10);
TF2 *f2a = new TF2("f2a","ROOT::Math::cauchy_cdf(x,y)",0,20, 0,20);
TF2 *f3a = new TF2("f3a","ROOT::Math::normal_cdf(x,y)",-10,10,0,5);
TF2 *f4a = new TF2("f4a","ROOT::Math::exponential_cdf_c(x,y)",0,10,0,5);
TCanvas *c1 = new TCanvas("c1","c1",800,650);
c1->Divide(2,2);
c1->cd(1); f1a->SetLineWidth(1);
f1a->Draw("surf1");
c1->cd(2); f2a->SetLineWidth(1);
f2a->Draw("surf1");
c1->cd(3); f3a->SetLineWidth(1);
f3a->Draw("surf1");
c1->cd(4); f4a->SetLineWidth(1);
f4a->Draw("surf1");
}
virtual void SetLineWidth(Width_t lwidth)
Set the line width.
