Mar 5, 2017 at 10:08 comment added Mr.Wizard @yode The third parameter of SparseArray sets the background element. The Normal form of the SparseArray will always look the same. Use ArrayRules to get a sense of how this works, e.g.: Table[ArrayRules @ SparseArray[Range@5, 5, i], {i, 5}]
Mar 5, 2017 at 10:05 comment added yode Could your tell me why I always get a same list Unitize[list - 2] // SparseArray[#, Automatic, AnyNumber] & // Normal?Change the AnyNumber
