Creating a distance matrix in Matlab?

Hello I am new to Matlab (I have used it in the past for basic and intermediate calculations).
My question is, does Matlab have a feature which allows one to create a distance matrix. I have the coordinates for several locations and I would like to find Manhattan distances. Is there any way to plot these coordinates to put in "obstacles" to represent actual distances?
Any suggestions?

Yes. bwdist. In fact, Steve is talking about it now on his blog: http://blogs.mathworks.com/steve/

On the Neural Network Toolbox™ you have the mandist function that seems to do what you need, if you don't have that toolbox try to adapt this to your needs Distance Matrix calculation by Zacharias Voulgaris
