SymbolicZerosArray

SymbolicZerosArray[]

represents an array of zeros with unspecified dimensions.

SymbolicZerosArray[{n₁,n₂,…}]

represents an n₁×n₂×… array of zeros.

Details

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