How do I create an array of structures for the POSITIVE_INSTANCES of the trainCascadeObjectDetector(outputxmlfilename,positiveinstances,negativeimages) function?? Having trouble understanding it and putting it together.

Try using the Cascade Training GUI. It is a MATLAB app that lets you label objects of interest in images and generate an array of structures of the same format as POSITIVE_INSTANCES.

As of release 2014a there is now a Training Image Labeler app in the Computer Vision System Toolbox. You can invoke it form the App Gallery or by typing

trainingImageLabeler

on the command line.
