Hi All,
I am working my way throgh the below ahrs filter fusion example but my version of matlab (2019a with Sensor Fusion and Tracking toolbox installed) seems to be having trouble recognising the function HelperOrientationViewer. Does anyone know if I require an additional toolbox to run this viewer or why this is not working?
Many thanks!
Ben

You may have to open the example in MATLAB and click the "Open Example" button. That will copy all necessary helper functions into a local folder for you to run the example.

Hi,
In the top right corner in the page, there is a 'Copy command' button. Clicking this button will copy the command required to open the example in MATLAB. Paste and execute the command in MATLAB command window.

Gayatri

Hi Ans Hafeez,
Which version of MATLAB are you using? The example is available in R2019a and above releases.

Hi there, I am having the same problem with this page https://au.mathworks.com/help/supportpkg/arduinoio/ug/estimating-orientation-using-inertial-sensor-fusion-and-mpu9250.html
However, I cannot see an option to 'Open iExample' in Matlab. Am I doing something wrong?
Thank you
Laura
