# SymbolicOnesArray

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.
