Are you having trouble with the math, or with the MATLAB? This wikipedia page for the confusion matrix can help you with all the definitions and their relationships. (The colorful table on that page is really helpful.)
To get the confusion matrix, you'll need to calculate the following:
  • true positive
  • false positive
  • true negative
  • false negative
I believe you should be able to derive those from the information you have. Write those explicit formulas out on paper. Then it should be extremely straightforward to convert those into MATLAB code.
