In case you are still searching :D

This code applies visibility graph method followed by dijkstras algorithm to find shortest path between two points, avoiding obstacles. The obstacles are difined as traingles, rectangles or zigzag lines (representing continous obstacles like a shore in a sea). If you have any questions dont hesistate to ask.

If you're trying to solve this problem where your data is elevation data and you have Mapping Toolbox available see this documentation page that list the los2 and viewshed functions. When I typed "@ doc:los" without the space to add that documentation link a number of other functions appeared: Antenna Toolbox and Communications Toolbox had los functions that may also be of interest.
