Dijkstra_Methode(Ma​trix, start, target)

This is the Dijkstra Methode implemented in Matlab for finding the shortest path.

With this Dijkstra Methode one can find the shortest path of an image.
(See here description http://physingo-en.blogspot.de/2016/12/matlab-dijkstra-methode-large.html)
function [path, prev, unvis, distance, start, target] = Dijkstra_Methode(Matrix, start, target)
Matrix is the incoming image
start is the start point in a vector [a,b] where a is the column and b the row
target is the end point similare to start
path is the matrix with ones excepted at the position of the path where it is 0
prev are also the previous visited pixels where the algorithm took the
wrong way
unvis are all unvisited pixels
distance is the distance or weight of the pixels
