# confusionMatrix

From RSNNS v0.4-12
by Christoph Bergmeir

##### Computes a confusion matrix

The confusion matrix shows how many times a pattern with the real class x was classified as class y. A perfect method should result in a diagonal matrix. All values not on the diagonal are errors of the method.

##### Usage

`confusionMatrix(targets, predictions)`

##### Arguments

- targets
the known, correct target values

- predictions
the corresponding predictions of a method for the targets

##### Details

If the class labels are not already encoded, they are encoded using `encodeClassLabels`

(with default values).

##### Value

the confusion matrix
