Share

Share[expr]
changes the way expr is stored internally, to try and minimize the amount of memory used.
Share[]
tries to minimize the memory used to store all expressions.
  • Share works by sharing the storage of common subexpressions between different parts of an expression, or different expressions.
  • Using Share will never affect the results you get from Mathematica. It may, however, reduce the amount of memory used, and in many cases also the amount of time taken.
