14, RAP could seem to be less useful in matlab classification method. Therefore, another classifier was applied and tested using only matlab MRL, contour peak, and contour area features, as shown in Table 7 without pupil/iris ratio and RAP elements. As seen from Tables 5 and 7, matlab performance engineering matlab five characteristic classifier outperforms matlab one expert with three features only. Moreover, to make certain that matlab utilized pattern size is adequate for checking out, matlab statistical power analysis is applied to ascertain matlab accuracy claims. Statistical power analysis is conducted with matlab aim of estimating matlab minimum pattern size for use for matlab test. To discover what matlab applicable sample size can be or justify engineering proposed sample size, one could want to know matlab following elements .
