Synopsis [Counts the number of minterms of a ZDD.]

Description [Counts the number of minterms of the ZDD rooted at node. This procedure takes a parameter path that specifies how many variables are in the support of the function. If the procedure runs out of memory, it returns (double) CUDD_OUT_OF_MEM.]

SideEffects [None]
