Return the transformation matrix between the volume specified by the path volumePath and the Top or mater volume.

The format of the path volumePath is as follows (assuming ALIC is the Top volume) "/ALIC_1/DDIP_1/S05I_2/S05H_1/S05G_3". Here ALIC is the top most or master volume which has only 1 instance of. Of all of the daughter volumes of ALICE, DDIP volume copy #1 is indicated. Similarly for the daughter volume of DDIP is S05I copy #2 and so on.

Inputs:
- TString& volumePath The volume path to the specific volume for which you want the matrix. Volume name hierarchy is separated by "/" while the copy number is appended using a "_".
Outputs:
- TGeoHMatrix &mat A matrix with its values set to those appropriate to the Local to Master transformation
Return:
- A logical value if kFALSE then an error occurred and no change to mat was made.

Outputs:
- TSrting &name Material name
- Int_t &imat Material index number
- Double_t &a Average Atomic mass of material
- Double_t &z Average Atomic number of material
- Double_t &dens Density of material [g/cm^3]
- Double_t &radl Average radiation length of material [cm]
- Double_t &inter Average interaction length of material [cm]
- TArrayD &par A TArrayD of user defined parameters.
Return:
- kTRUE if no errors
