Accuracy = (TP+TN)/(TP+TN+FP+FN)
where: TP = True positive; FP = False positive; TN = True negative; FN = False negative
As you can find on Wikipedia ( https://en.m.wikipedia.org/wiki/Accuracy_and_precision )
So it should be trivial to calculate the accuracy from your confusion matrix: divide the sum of the diagonal by the total sum.
