simplify simplify_fractions maybe too weak for polyform #399

Closed liushang0322 closed 2 years ago

liushang0322 commented 2 years ago

Another problem is that when the expression has many operations, it is difficult to simplify the expression to something like matlab, especially when numden is used in matlab, the arguments seem to be very weak, and only a single operator can be simply taken out. Operands, but cannot be decomposed well, especially when the final form is polynomial/polynomial.

I could not figure out what the problem is from your description. Could you please post an example?
