The scalar Indexing Function
The scalar indexing function can be used to construct rtable objects of type Array, Matrix, or Vector.
In the construction of a Matrix, the scalar[x] indexing function specifies a Matrix whose entries have the value x on the main diagonal and the value 0 everywhere else.
The specification is the same in the construction of an Array.
In the construction of a Vector, the scalar[j, x] indexing function specifies a Vector which has the value x for entry j and the value 0 everywhere else.
Under normal circumstances, Maple only stores the value of x. To override this, specify a storage value.
V ≔ Vector⁡5,shape=scalar2,3
M ≔ Matrix⁡1..4,1..4,shape=scalar3
