how to use syntax "sdo.ParameterSpace"

I try to do sensitivity analysis in my study case. Because my result of simulink design optimization had some problems in design variables. So i followed the guide "Sensitivity Analysis of simulink design optimization" to type code to do. But in the "sdo.ParameterSpace" syntax, the matlab command window showed the error of Undefined variable "sdo" or class "sdo.ParameterSpace". So what is wrong with me? Could someone offer some suggests for me. Thanks

Could it be that you do not have a license of Simulink Design Optimization? Please type

>>ver

and see if Simulink Design Optimization is in the list, and if it is, what version do you have. Sensitivity analysis capabilities were introduced in R2014a, so unless you have this latest version, you won't be able to do it.

As you know, my version is R2012b. does it mean that i would not use any syntax about sensitivity analysis? but i still have some questions about sensitivity. according to the Sensitivity Analysis

sdo.getParameterFromModel Design variable for optimization sdo.getStateFromModel Initial state for estimation from Simulink model sdo.sample Generate parameter samples sdo.evaluate Evaluate cost function for samples sdo.analyze Analyze how model parameters influence cost function sdo.scatterPlot Scatter plot of samples makedist Create probability distribution object sdo.ParameterSpace Specify probability distributions for model parameters

i could use sdo.getParameterFromModel , sdo.getStateFromModel & sdo.ParameterSpace why could i use those syntax in R2012b? thanks for you help

I actually did not know your version until you provided that info. Again, sensitivity analysis capabilities did not exist in R2012b, so you would not be able to use them in that release. To see which commands are available in R2012b please refer to doc in the product itself, or online here and here .
