According to the error message, your x is a handle of a figure. Then real() is not defined to convert it.

If you post the related code, we might be able to see, why you assume that x has a numerical value.

Please read http://www.mathworks.com/matlabcentral/answers/13205-tutorial-how-to-format-your-question-with-markup
I've removed the posted code. There is no reason to publish the copy-righted code of int2str(), but the problem is found in the code, which calls this function. Why does your code try to convert a figure handle to a string in the function PlotRay, line 52?
