Detailed Description

Renumber indices to lowest possible index.

For example:

\( \begin{bmatrix} 0 & 1 \\ 5 & 4 \end{bmatrix} \)

is renumbered to

\( \begin{bmatrix} 0 & 1 \\ 3 & 2 \end{bmatrix} \)

Or, in pseudo-code, the result of this function is that:

 dofs = renumber(dofs)
 sort(unique(dofs[:])) == range(max(dofs+1))

Note

One can use the wrapper function renumber(). This class gives more advanced features.
