Detailed Description

Compute the actual size of variable block size algebraic elements.

This class will refer to scalarized sizes, which means the actual size of the algebraic elements, as if it was not a block element. For exemple, a vector with two block 2x1 entries has a size of two and a scalarized size of four (2 elements for each block).
