Error regarding the stateEstimatorPF

I am using MATLAB R2017a. When I type the command, It gives an error. Although it is written that the command is introduced in R2016a. And I am having latest version of MATLAB. Kindly guide me how do I proceed?

COMMAND:
pf = stateEstimatorPF
ERROR:
Undefined function or variable 'stateEstimatorPF'.

Error in xxx (line 21)
 pf = stateEstimatorPF

Hi Sameema,

Please ensure that you have Robotics System Toolbox.

I see the reason of erroring out while using the stateEstimatorPF from R2017a MATLAB. This stateEstimatorPF object is available from R2019b, but the functionality of what that object does is introduced from R2016a.

This information can be known from the documentation page of https://www.mathworks.com/help/nav/ref/stateestimatorpf.html#mw_1bb777c8-2df4-4f80-bb50-8968011c4976

You can use the robotics.ParticleFilter object to perform this task from R2017a.

Hope this helps.

Regards,

Sriram

Can you make sure you have Robotisc System Toolbox? Try this

ver robotics

If you could see Robotics System Toolbox installed, try this

edit robotics.ParticleFilter

If this opens, then you could be able to work with the file.
