SymbolicOnesArray

SymbolicOnesArray

New in 14.1[Experimental]

✖

represents an array of ones with unspecified dimensions.

✖
SymbolicOnesArray[{n1,n2,…}]

represents an n1×n2×… array of ones.

Details

  • Valid dimension specifications ni in SymbolicOnesArray[{n1,n2,…}] are positive integers. It is also possible to work with symbolic dimension specifications.
  • SymbolicOnesArray may be produced by arithmetic operations and differentiation involving ArraySymbol objects.
  • For an array a=SymbolicOnesArray[{n1,n2,…}] with positive integer dimension specifications ni, Normal[a] converts a to an explicit array. SparseArray[a] converts a to a SparseArray.
