This function calculates the overlap of clusters
produced by `mfuzz`

.

1 | ```
overlap(cl)
``` |

`cl` |
object of class |

The function generates a matrix of the normalised overlap of soft clusters. The overlap indicates the extent of “shared” genes between clusters. For a mathematical definiton of the overlap, see the vignette of the package or the reference below.
