Is there a matlab function to read in a *.fit file from a Garmin device?

Garmin GPS watches record a variety of parameters during running, cycling, and swimming. The parameters are all recorded in *.fit files. These files are read into different user interfaces (e.g., Garmin Connect).

I would like to read the file directly into matlab in order to process them.

I found a web site that does this: http://www.rainorshine.bike/

But this is time consuming to do one file at a time.

Has anyone created a matlab function to accomplish this?

I need this too. Thanks for web link!

Can you export to GPX instead? https://www.mathworks.com/help/map/ref/gpxread.html If not then convert to GPX using perl: https://www.bikeforums.net/electronics-lighting-gadgets/1071030-garmin-fit-gpx-sigma-slf-conversion.html (perl is included with MATLAB.)

This link suggests you should be able to run some java code: https://forums.garmin.com/forum/developers/device-communications/garmin-device-interface-sdk/13986-

you can convert the files with the included tool in the Garmin's SDK:

https://developer.garmin.com/fit/cookbook/decoding-activity-files/

or well, you can write your own matlab code to decode de FIT data.

The documentation is here:
