I have the below code and answers
[C,order] = confusionmat(exPostDS.Passed_1,predDS.PredRating)
C =
638 62
151 149
order =
'1'
'2'
I would like to know if I can get to know what the values 62 and 151 hold in terms of separate rows. All values are clients which I would like to know at least the ClientID.
Is it possible to be done?

If I run this code:
load fisheriris
x = meas;
y = species;
yhat = classify(x,x,y);
[cm,order] = confusionmat(y,yhat);
the confusion matrix cm indicates a count of 2 in the [2,3] entry. Here's how I can locate those two rows:
find(strcmp(y,order{2}) & strcmp(yhat,order{3}))
Here my variables y and yhat are cell arrays of strings. You may have to adjust this if your inputs to confusionmat are different data types.

How do I calculate the sensitivity and specificity with the confusionmat command? What is the position of TP, FP, FN, TN in the confusion matrix provided by matlab? I use "confusionmat".
