32 // Class description:
33 //
34 // Class for creation of quadrupole magnetic field
35 // fGradient - is the gradient value for quadrupole magnetic lense.
36 // Then the magnetic field components are:
37 // Bx = B[0] = fGradient*X ,
38 // By = B[1] = fGradient*Y ,
39 // Bz = B[2] = 0 .
40 // Here X,Y,Z are the coordinates of a space point of interest.
41 
42 // History:
43 // 3.2.97 - V.Grichine, created.
44 // 11.5.12 - B. Riese allow displaced origin and rotation (Björn Riese)
