Subject: Computing euclidean distances between every row of a position matrix From: Kelsey Date: 31 May, 2011 21:13:02 Message: 1 of 8 
I'm new to MATLAB and have been learning how to program with it through Internet research and trial/error. I have a matrix that contains position data (columns are x, y, and z, and rows are each node on the graph.) I would like to create an N*N matrix (where N is the number of nodes on the graph) where each entry is the euclidean distance between the nodes specified by the indices of that entry. I know that I want to use a biograph object so that I can use the allshortestpaths function to get the distance matrix I want, but I need help creating the biograph object and connection matrix and somehow loading it with all of my position data so that I can use the allshortestpaths function.

No idea what a biograph object is, but here's what I use:
