I am using ArcMap 10.4.1.


I want to manually calculate the transformation (WKID 1515) using the values from the Transformation Tables.  I am familiar with matrices and can easily apply the 3 or 7 parameter method.  I believe what ESRI is describing as the "Position Vector" method would use the matrices formulation.  However, the WKID 1515 is only given as a "Coordinate Frame" method.  Can I assume the dx, dy, dz...values tabulated for the Coordinate Frame method could also be used in the matrices formulation to solve the transformation ?  If not, does ESRI have the tabulated parameters for the other methods ?
