Calculate the coranking matrix, to assess the quality of a
dimensionality reduction. Xi
is input in high dimensions,
X
is input in low dimensions the type of input is given in
input
, if input = 'data'
it will be transformed into
a distance matrix with the dist
function, id input ==
'rank'
, Xi
and X
are expected do be rank matrices.
a matrix of class 'coranking'
