Set up Identity File (i.e. ssh key) for batch submission

I use the batch command to submit job to a cluster and take advantage of the parallel computing toolbox.

I set up an ssh key pair that allows me to connect to the cluster without being prompted for my password.

When using the batch command in Matlab, I am prompted for my cluster user name, after which I can either

1. choose a so-called identity file (i.e. private ssh key)
2. or type my password

solution 1. works, however, I have to input user name and the file containing the private ssh key every time the batch command is used.

How could I save user name and path to these key file so that I dont have to enter them every time, even after restarting Matlab?

I imagine it should be possible to save this information in the used Cluster Profile but cannot find out where.

[TZ]

To solve this I have set AdditionalProperties in my cluster profile in such order:

Name | Value | Type

ClusterHost | mycluster.de | String

IdentityFile | D:\id_rsa | String

IdentityFileHasPassphrase | false | Logical

UseIdentityFile | true | Logical

Username | joe | String

(Assuming I log onto my cluster by [e-mail] and my cluster admin supplied me with a rsa private key named id_rsa which I saved on D:)
