====== Calc Confusion Matrix ======

===== Description =====

Calculates the [[wp>Confusion_matrix|confusion matrix]] from two input maps. The confusion matrix is a table with format "Initial*#real, Final*#real and Changes#real" mapping each possible combination of pair of input map values to their corresponding number of cells.

===== Inputs =====

^ Name  ^ Type  ^ Description  ^
| Initial Map  | [[Categorical Map Type]]  | The initial map. This map corresponds to the "Initial" key column of the resulting table.  |
| Final Map  | [[Categorical Map Type]]  | The final map. This map corresponds to the "Final" key column of the resulting table.  |

===== Output =====

^ Name  ^ Type  ^ Description  ^
| Confusion Matrix  | [[Table Type]]  | Resulting confusion matrix. The confusion matrix is a table with format "Initial*#real, Final*#real and Changes#real" mapping each possible combination of pair of input map values to their corresponding number of cells.  |

===== Notes =====

If the input maps are completely filled with null values or if there is no non-null intersection between them, an empty confusion matrix will be returned.
