I am woking with Matlab 2018b. Installed with Sensor fusion and Tracking Toolbox and Automated Driving Toolbox.

Considering the examples on the Matlab website

https://www.mathworks.com/help/fusion/ref/insfilter.html

The inbuilt function "filt = insfilter" does work with two examples

nhFilter = insfilter('NonholonomicHeading',true, ...
                     'Magnetometer',false)
filter = insfilter

The other examples doesn't work.

Is it possible to reinstall the Toolbox on Matlab 2018b or any other solution so that all examples can work on matlab version 2018b?

or the rest of examples are only available in the new version of 2019a??

filter = insfilter("errorstate")
filter = insfilter("asyncimu")
nhFilter = insfilter('NonholonomicHeading',true, ...
                     'Magnetometer',false, ...
                     'AsyncIMU',false, ...
                     'ErrorState',false)

Thank you very much in advance.

Please explain what "doesn't work" means. Do you get an error message?

Use the local documentation of your Matlab installation to find out, which features are available. Using examples from another Matlab release can cause confusions. Do these examples occur, if you type:

doc insfilter

?

As Jan suspected, the insfilter function has additional capabilities in release R2019a (the current release.) The online documentation is for the current release. According to the Release Notes the 'errorState' and 'asyncIMU' input arguments are new in R2019a.
