Create a roadrunner object, specifying the path to an existing project. For example, this code shows the path to a project, on a Windows® machine, located at "C:\RR\MyProject". This call assumes that RoadRunner is installed in the default location, and returns an object, rrApp, that provides functions for performing basic workflow tasks such as opening, closing, and saving scenes and projects.
Open an existing scenario in the specified project by using the openScenario function, specifying the rrApp object and the specific scenario filename that you want to open as inputs.
Set the value of a scenario variable. Call the setScenarioVariable function and pass it the rrApp object, the variable whose value you want to set, and the value that you want to assign to the variable. For example, this call assigns a value of 17.88 m/s as the initial speed of the Ambulance in the scenario MyScenario.
name = "Ambulance_InitialSpeed";
value = "17.88";
setScenarioVariable(rrApp,name,value)
RoadRunner application associated with a project, specified as a
roadrunner object. This object provides functions
for performing common workflow tasks such as opening, closing, and saving scenes and
projects. rrApp provides functions that support importing data from
files and exporting scenes to other formats from RoadRunner.
Name of variable to set, specified as a character vector or string scalar. If the
specified variable does not exist in the scenario, MATLAB® returns an error. For more details on creating variables in a scenario,
see Generate Scenario Variations.
Example: setScenarioVariable(rrApp,"Ambulance_InitialSpeed",17.88)
sets the initial speed of the Ambulance vehicle.
Value to assign to the variable, specified as a character vector, string scalar,
logical scalar, or numeric scalar. This argument specifies the new value of the scenario
variable specified by name.
Example: setScenarioVariable(rrApp,"Ambulance_InitialSpeed",17.88)
sets the initial speed of the Ambulance to 17.88
m/s.
