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
}}}
