Description

Sometimes Mathematica computes huge output expressions which are hard to examine. The function IPX[] replaces all terms and coefficients that contain none of the given variables with ONE replacement variable. The result is a more readable expression regarding the specified variables.

The expression manipulations such as Simplify, Together, Collect... are more effective, because you can see clearly an existing pattern. Furthermore the simplified expression makes a coefficient comparison possible.

The notebook contains some examples of the usage of IPX[]. It uses the Package IPX.m.
