+With this method, you can submit MATLAB jobs from MATLAB running on an interactive session. See how to run MATLAB interactively [https://wiki.hpc.tulane.edu/trac/wiki/cypress/Matlab#RunningMATLABinteractively here].

+
+=== Configuration ===
+Login to Cypress and start an interactive session and then start MATLAB (see [https://wiki.hpc.tulane.edu/trac/wiki/cypress/Matlab#RunningMATLABinteractively here])
+Configure MATLAB to run parallel jobs on your cluster by calling '''configCluster''', which only needs to be called once per version of MATLAB.  
+Please be aware that running '''configCluster''' more than once per version will reset your cluster profile back to default settings and erase any saved modifications to the profile.  
+
+{{{
+>> configCluster
+}}}
+
+Jobs will now default to the cluster rather than submit to the current node.
+
+When you encounter an error ''Unrecognized function or variable 'configCluster'. '', try
+
+{{{
+>> rehash toolboxcache
+}}}
+
+
+
+== INTERACTIVE JOBS - MATLAB client on Cypress ==
+ Note this is for '''MATLAB client on Cypress'''.
+
+To run an interactive pool job on the cluster, continue to use parpool as you’ve done before.
+{{{
+>> % Get a handle to the cluster
+>> c = parcluster;
+}}}
+{{{
+>> % Open a pool of 4 workers on the cluster (works up to 12?)
+>> p = c.parpool(4);
+}}}
+Rather than running local on the local machine, the pool can now run across multiple nodes on the cluster.
+{{{
+>> % Run a parfor over 1000 iterations
+>> parfor idx = 1:1000
+      a(idx) = idx
+   end
+}}}
+Once we’re done with the pool, delete it.
+{{{
+>> % Delete the pool
+>> p.delete
+}}}
