I have used the following function for finding confusion matrix c=confusionmat(x,y)
it gives me output like that ,
C =
0 4 0 0
0 0 0 0
0 0 0 0
0 0 4 0
now i want to find accuracy and f_measure from this confusion matrix

The F-statistic is a different matter (a Google search should help you find a way to calculate that), but since there are no values on the diagonal, you can immediately see that the accuracy is 0.
