MatrixElementsCollect File-1 File-2 ...
MatrixElementsCombine File-1 File-2 ...
MatrixElementsCollect reads T-matrix elements from
an external file and puts them into an internal data structure.
MatrixElementsCombine reads T-matrix elements from
an external file and combines them with matrix elements that have already read in for the same symmetry
and energies. This is used to replace the low partial wave matrix elements with more accurate values.
If the variables File-n are present, then the T-matrix elements in
those files are processed. Otherwise, the program use the automatically generated
scratch file as described in the definition of the command
