setIndexedMatrix!

setIndexedMatrix!(X, [on=true])

X is a matrix with row labels and column labels. Row labels and column labels must be monotonically increasing with no duplicate values.

on (optional) is a Boolean value indicating the conversion between a matrix and an indexed matrix. The default value is true, indicating the conversion from a matrix to an indexed matrix. Set to false for the opposite conversion.

Set the labels of the rows and columns of a matrix as the indexes.
