load (serial) (External Interfaces Reference)

Load serial port objects and variables into the MATLAB workspace

Syntax

load filename
load filename obj1 obj2...
out = load('filename','obj1','obj2',...)

Arguments

filename
The MAT-file name.

obj1 obj2...
Serial port objects or arrays of serial port objects.

out
A structure containing the specified serial port objects.

`filename`	The MAT-file name.
`obj1 obj2...`	Serial port objects or arrays of serial port objects.
`out`	A structure containing the specified serial port objects.

Description

load filename returns all variables from the MAT-file specified by filename into the MATLAB workspace.

load filename obj1 obj2... returns the serial port objects specified by obj1 obj2 ... from the MAT-file filename into the MATLAB workspace.

out = load('filename','obj1','obj2',...) returns the specified serial port objects from the MAT-file filename as a structure to out instead of directly loading them into the workspace. The field names in out match the names of the loaded serial port objects.

Remarks

Values for read-only properties are restored to their default values upon loading. For example, the Status property is restored to closed. To determine if a property is read-only, examine its reference pages.

Example

Suppose you create the serial port objects s1 and s2, configure a few properties for s1, and connect both objects to their instruments:

s1 = serial('COM1');
s2 = serial('COM2');
set(s1,'Parity','mark','DataBits',7);
fopen(s1);
fopen(s2);

Save s1 and s2 to the file MyObject.mat, and then load the objects back into the workspace:

save MyObject s1 s2;
load MyObject s1;
load MyObject s2;

get(s1, {'Parity', 'DataBits'})
ans = 
    'mark'    [7]
get(s2, {'Parity', 'DataBits'})
ans = 
    'none'    [8]
