##### Usage

`distanceHadamard(dm, eps = 0.001)`

##### Arguments

- dm
A distance matrix.

- eps
Threshold value for splits.

##### Value

`distanceHadamard`

returns a matrix. The first column contains
the distance spectra, the second one the edge-spectra. If eps is positive an
object of with all splits greater eps is returned.
