I have data that looks like this

GRr  GPr  GYr
-208  223  -13
227  -210  114
216  165  -72
-198  16  242
-243  248  -24
-52  -189  219
82  1  167
10  54  198
20  20  179
-44  -183  28
-229  49  186
-71  -10  -36
-249  15  194
61  241  -68
150  14  233
-43  -233  107
-35  -224  59

The data represents the movement of a joycon controller every 100 milliseconds. I would like to be able to look at the frequency and magnitude of the movement in 1 second timebins. Does anyone have any advice on how I would do this in matlab - such as what functions I would use. I have resting noise profiles for each column (+ or - 2std )

The retime (link) function, specifically the method described in Aggregate Timetable Data and Calculate Mean Values (link) would be how I would approach it.
