Run MATLAB code from Phloem. The agent and Computer can evaluate expressions, run scripts and read variables back.

#What you get

• Operations — eval (run an expression), run_script, and get_variable (run code and read one variable back), plus a connection test.
• Each call runs MATLAB headless (matlab -batch) on its own. Nothing carries over between calls.

#Setup

1. Install the connector from the Connectors tab and open its page.
2. Point it at your MATLAB installation, then press Test to confirm.

#Computed channels

A computed channel runs your function over a window of a signal and publishes the result as a new channel. Your function gets one window struct:

Copyfunction result = my_metric(win)
  % win.t_us  — sample times, microseconds since 1970-01-01 UTC
  % win.value — the sample values, same order
  result = max(win.value) - min(win.value);
end

Return one number, or a struct of names to numbers for several outputs. Times are microseconds; divide by 1e6 for seconds.

#Notes

• Put everything a computation needs in one eval. get_variable takes the code that sets the variable and its name, and runs both in one call.
• A call that runs too long is stopped, along with anything MATLAB started.
• A sample with no reading arrives in win.value as NaN.

#Connection fields

Every field the Add input form shows for this connector.
