get

Read variables from connected data source

Since R2024a

Syntax

get(connectionObj,varNames)

Description

get(connectionObj,varNames) returns the values of the specified variables varNames. The function returns a missing value, displayed as <missing> for variables that are not defined in the connected data source.

If the data connection can see multiple definitions of the same variable (for example, in a data dictionary and in a referenced dictionary), the function reports an error if the definitions of the variable are inconsistent. For multiple consistent definitions, the function returns the value of one of the variable definitions.

Examples

Read Variable From Model Workspace

mw = Simulink.data.connect("myModel.slx");
set(mw, 'b', 2);
get(mw, 'b')

ans = 

    2

Read Multiple Variables From Model Workspace

mw = Simulink.data.connect("myModel.slx")
set(mw, {'e','f'}, {5,6});
get(mw, {'e', 'x', 'f'})

ans = 

1x3 cell array

    {[5]}    {[<missing>]}    {[6]}

Input Arguments

connectionObj — Connection to data source

Simulink.data.DataConnection object

Connection to data source, specified as a Simulink.data.DataConnection object.

varNames — Variable names

string | character vector | array of strings | cell array of character vectors

Variable names, specified by a string, character vector, array of strings, or cell array of character vectors.

Tips

You can also read and assign values to variables by using the . operator. For example, to read a variable from a data dictionary:

dd = Simulink.data.connect('myDictionary.sldd');
dd.x = 1;
dd.x

ans = 

     1

dd.b

ans = 

  missing

    <missing>
