Note also that dist is part of the neural network toolbox, and if you have that toolbox you are not calling dist correctly. Pairwise distance between pairs of observations matlab pdist. You can create a standard network that uses dist by calling newpnn or newgrnn to change a network so an input weight uses dist, set putweightsi,j. For each pixel in bw, the distance transform assigns a number that is the distance between that pixel and the nearest nonzero pixel of bw you optionally can compute the euclidean distance transform of a 2d binary image using a gpu requires parallel computing toolbox. A read is counted each time someone views a publication summary such as the title, abstract, and list of authors, clicks on a figure, or views or downloads the fulltext. With this distance, euclidean space becomes a metric space. Euclidean distance varies as a function of the magnitudes of the observations.
