It compares 'actual' and 'predicted' value columns. Rows represent actual values, columns represent predicted values. Input values are small, contiguous integers starting from 0. An optional 'order' list defines the expected values, dictating matrix dimensions and order. If 'order' is unspecified values are assumed to be contiguous from 0 to a maximum value. The input collection is a FeatureCollection.\n"]]
