Data you want to associate with a serial port object


You configure UserData to store data that you want to associate with a serial port object. The object does not use this data directly, but you can access it using the get function or the dot notation.

Data type

Any type


The default value is an empty vector.


Suppose you create the serial port object associated with the serial port COM1.

s = serial('COM1');

You can associate data with s by storing it in UserData.

coeff.a = 1.0;
coeff.b = -1.25;
s.UserData = coeff;
