I'm trying to develop several visualization of tools for a network of individuals (nodes). For example, one tool computes the (user input) number of smallest distances between each node and every other node, and then plots arrows between nodes that are sensing each other (they sense each other one is a shortest distance away from another). Some edges are directed because the sensing only travels in one direction, and some are undirected because the sensing goes both ways--each member of the pair connected is one of each other's nearest neighbors. Now, I'm trying to make a tool that finds independent groups nested inside the larger network. To do this, I want to traverse the array of node pairs (both directed and undirected), and track each "node path". So, say the first pair is 1 6. Then I want to find where 6 appears in the first column and use whatever is in the column next to it
as the connector. If what is in the second column is ever the first node that we started with, then there's a complete path, which means that those pair connections define an independent group within the larger network. I'm having trouble coding this because the code doesn't seem to be updating. Here's what I have so far:
nodePath(j,:) = directedEdges(i,:);
nodeConnection = nodePath(j,2);
while nodeConnection ~= nodePath(i,1)
[nodeSensor,nodeSensed] = find(directedEdges(:,1)==nodeConnection);
nodePath(j,:) = directedEdges(nodeSensor,:);
nodeConnection = nodePath(j,2);
^this is what I need help with. I don't know how to change the assignment statements so that the code properly checks every node path to see if it's an independent cycle.
% if there's a complete cycle, plot it: this code works.
if nodeConnection == nodePath(i,1)
directedEdgesCycle = nodePath;
xVal1 = x(directedEdgesCycle(k,1));
xVal2 = x(directedEdgesCycle(k,2));
f(j) = xVal2 - xVal1;
yVal1 = y(directedEdgesCycle(k,1));
yVal2 = y(directedEdgesCycle(k,2));
g(j) = yVal2 - yVal1;
zVal1 = z(directedEdgesCycle(k,1));
zVal2 = z(directedEdgesCycle(k,2));
h(j) = zVal2 - zVal1;
xplotdcycle = x(directedEdgesCycle(:,1));
yplotdcycle = y(directedEdgesCycle(:,1));
zplotdcycle = z(directedEdgesCycle(:,1));
f = transpose(f);
g = transpose(g);
h = transpose(h);
Any help would be greatly appreciated, thank you.
You can think of your watch list as threads that you have bookmarked.
You can add tags, authors, threads, and even search results to your watch list. This way you can easily keep track of topics that you're interested in. To view your watch list, click on the "My Newsreader" link.
To add items to your watch list, click the "add to watch list" link at the bottom of any page.
To add search criteria to your watch list, search for the desired term in the search box. Click on the "Add this search to my watch list" link on the search results page.
You can also add a tag to your watch list by searching for the tag with the directive "tag:tag_name" where tag_name is the name of the tag you would like to watch.
To add an author to your watch list, go to the author's profile page and click on the "Add this author to my watch list" link at the top of the page. You can also add an author to your watch list by going to a thread that the author has posted to and clicking on the "Add this author to my watch list" link. You will be notified whenever the author makes a post.
To add a thread to your watch list, go to the thread page and click the "Add this thread to my watch list" link at the top of the page.
The newsgroups are a worldwide forum that is open to everyone. Newsgroups are used to discuss a huge range of topics, make announcements, and trade files.
Discussions are threaded, or grouped in a way that allows you to read a posted message and all of its replies in chronological order. This makes it easy to follow the thread of the conversation, and to see what’s already been said before you post your own reply or make a new posting.
Newsgroup content is distributed by servers hosted by various organizations on the Internet. Messages are exchanged and managed using open-standard protocols. No single entity “owns” the newsgroups.
There are thousands of newsgroups, each addressing a single topic or area of interest. The MATLAB Central Newsreader posts and displays messages in the comp.soft-sys.matlab newsgroup.
You can use the integrated newsreader at the MATLAB Central website to read and post messages in this newsgroup. MATLAB Central is hosted by MathWorks.
Messages posted through the MATLAB Central Newsreader are seen by everyone using the newsgroups, regardless of how they access the newsgroups. There are several advantages to using MATLAB Central.
Your MATLAB Central account is tied to your MathWorks Account for easy access.
Use the Email Address of Your Choice
The MATLAB Central Newsreader allows you to define an alternative email address as your posting address, avoiding clutter in your primary mailbox and reducing spam.
Most newsgroup spam is filtered out by the MATLAB Central Newsreader.
Messages can be tagged with a relevant label by any signed-in user. Tags can be used as keywords to find particular files of interest, or as a way to categorize your bookmarked postings. You may choose to allow others to view your tags, and you can view or search others’ tags as well as those of the community at large. Tagging provides a way to see both the big trends and the smaller, more obscure ideas and applications.
Setting up watch lists allows you to be notified of updates made to postings selected by author, thread, or any search variable. Your watch list notifications can be sent by email (daily digest or immediate), displayed in My Newsreader, or sent via RSS feed.
