Mathworks example A* pathfinding algorithm problems

Im using Mathworks' A* pathfinding algorithm and attempting to modify it so that it searches through a map that is constantly becoming more available. The ginput command given in the script for inserting start point, end point and obstacles produces them as cartesian coordinates but due to the nature of my surrounding code (I treat the map so to speak as a 2D matrix therefore matrix indecies used), I am not getting the results desired. Is there a way to either insert my points manually as cartesian coordinates or change the format of the matrix to be cartesian based?

I'm sure there is.

Hi Rhys,

You can find a few examples of A* algorithm implentation in MATLAB from here - link1 and link2.

You can make changes in the above File Exchange codes to manipulate the code to insert the points as cartesian co-ordinates.
