* \brief Represents a sequence of

(row/column interchange)

* \param SizeAtCompileTime the number of
transpositions
, or Dynamic
21
* \param MaxSizeAtCompileTime the maximum number of
transpositions
, or Dynamic. This optional parameter defaults to SizeAtCompileTime. Most of the time, you should not have to specify it.

* This class represents a permutation transformation as a sequence of \em n
transpositions
29
* Compared to the class PermutationMatrix, such a sequence of
transpositions
is what is

* To apply a sequence of
transpositions
to a matrix, simply use the operator * as in the following example:

*
Transpositions
tr;

* In this example, we detect that the matrix appears on both side, and so the
