To add clarification: The Resourcesubmit line is an exact copy of the error message as it appears; the message was contracted by the system. Perhaps if the error message was rendered fully it might help me identify the problem, but as it is, the error message has not been helpful,
I have made many edits of the MatrixDecomposition.wl file since submitting this request for help, to no avail. The error message seems to suggest a problem with Private
keyword, which appears only in the Begin[] command in the MatrixDecomposition.wl file.
