clearAllVariables

Clear variables from data source workspace

Since R2022b

Syntax

clearAllVariables(dsWks)

clearAllVariables(dsWks) clears the variables from the data source workspace represented by the Simulink.data.DataSourceWorkspace object dsWks.

Add some variables to a data source workspace.

setVariable(sourceWorkspace,'b', 2);
setVariables(sourceWorkspace,["c" "d"], {3,4});
setVariables(sourceWorkspace,{'e','f'}, {5,6});

Now return the list of variables that are contained in the workspace.

vars = listVariables(sourceWorkspace);
vars

vars
  5x1 string array

    "b"
...."c"
...."d"
    "e"
    "f"

Clear the variables from the workspace.

clearAllVariables(sourceWorkspace);

Now return the list of variables again and confirm that the workspace is empty.

vars = listVariables(sourceWorkspace);
vars

vars
  0x1 empty string array

Data source workspace, specified as a Simulink.data.DataSourceWorkspace object.

Introduced in R2022b
