Similar to TCL::trasat
from the CERN program library this function implements a matrix product `(T+I)G(T+I)' -> G` where G is a symmetric 6x6 matrix packed in a 21 = 6(6+1)/2 element array, T and T' are a transformation matrix and its transpose respectively. Unlike TCL::trasat
this function assumes that a unit matrix I
is added to the transformation matrix T
in order to avoid calculations with near zero diagonal elements. One can subtract a unit matrix from F = T+I
before feeding it to errPropag6
in order to get results identical to TCL::trasat
for the same T
.
