Creating an Array of Serial Port Objects

In MATLAB, you can create an array from existing variables by concatenating

those variables together. The same is true for serial port objects. For example,

suppose you create the serial port objects

s1 and s2

s1 = serial('COM1');

s2 = serial('COM2');

You can now create a serial port object array consisting of s1 and s2 using the

usual MATLAB syntax. To create the row array

x = [s1 s2]

Instrument Object Array

Index: Type: Status: Name:

1 serial closed Serial-COM1

2 serial closed Serial-COM2

To create the column array y

y = [s1;s2];

Note that you cannot create a matrix of serial port objects. For example, you

cannot create the matrix

z = [s1 s2;s1 s2];

??? Error using ==> serial/vertcat

Only a row or column vector of instrument objects can be created.

Depending on your application, you may want to pass an array of serial port

objects to a function. For example, to configure the baud rate and parity for

and

s2 using one call to set

set(x,'BaudRate',19200,'Parity','even')

Refer to the serial port function reference to see which functions accept a serial

port object array as an input.
