### 3.10 Distribute Octave variables

Function File: install_vars `(varname, …, connections)` ¶

  Install named variables at remote machines.

  The variables named in the arguments are distrubted to the remote machines specified by connections and installed there. The variables must be accessible within the calling function. If variables have been declared to have global scope, they will also have global scope at the remote machines.

  This function can only be successfully called at the client machine. See `pconnect` for a description of the connections variable. connections can contain all connections of the network, a subset of them, or a single connection. The local machine (client), if contained in connections, is ignored.

  To install, e.g., all visible variables,

  `install_vars (who (){:}, …);`

  can be used.

  Internally, this function sends the variables only to one server and then issues the necessary commands to distribute them to all specified servers over server-to-server data connections.
