BUILT-IN MATHEMATICA SYMBOL
changes the way expr is stored internally, to try and minimize the amount of memory used.
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.
- Share returns the number of bytes freed as a result of sharing, as determined by MemoryInUse.
Try to minimize memory used in all expressions:
Use shared memory for parts of an expression that are the same:
This is effectively the same as creating the expression using shared parts:
For this expression, Share is not able to save any more memory:
