set

Assign variable in connected data source

Since R2024a

Syntax

set(connectionObj, varNames, varValues)

Description

set(connectionObj, varNames, varValues) assigns values to variables 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 updates the value for all definitions of the variable. If the variable does not exist in a data source visible to the data connection, then the function creates the variable in the directly connected data source.

Examples

Assign Variable in Model Workspace

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

ans = 

    2

Assign Multiple Variables in 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.

varValues — Variable values

integer | vector of integers

Variable values, specified as an integer or a vector of integers matching the dimension of varNames. The order of variable values corresponds to the order of the variables specified in varnames.

Tips

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

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

ans = 

     1
