Fill Elements

When MARPLE needs to pad arrays to uniform shape (for example during rank-operator reassembly), it uses fill elements:

Array type Fill element
Numeric 0
Character ' ' (space)
Boolean 0

Where fill elements are used

  • Rank operator reassembly: when result cells from f⍤k differ in shape, shorter cells are padded with fill elements to match the largest cell shape.
