Modified the code to work with Octave 3.6.4 in Windows

[tjrantal]

Some of the features in the code weren't implemented in Octave version 3.6.4, so I modified the code so that the Script.m runs through in Octave in Win7.

On a related note, thank you for publishing the code! I'm going to start using an IMU for assessing physical performance as affordable (not to mention more portable and convenient) alternative to a force plate (which is what I've used in the past). Dr. Madgwick's method ought to work as is, and saved me a lot of unnecessary re-inventing the wheel (assuming that I would've ever gotten there, which is not a given). I will cite Dr. Madgwick's thesis and/or the paper indicated in x-io Technologies web page when I publish my work (in a couple of years :) ). Please let me know if you'd prefer some other references to be cited.

Wuju, forgive my unprofessional excitement.

Hello Thomas,

I haven't worked with the code in 5 years and am currently using different code to work with x-io data. What are you trying to achieve? I might be able to give you a leg up. If it's specifically on position tracking, then I'm not able to help.

On a related note, I'm on my summer holiday so will be slow to respond.

Regards, -Timo

Hi mate,

Is there any update on this project?

I tried to run script.m on Octave 5.1.0. It fails when loading the dataset. In Matlab, this step works right of the box.

Do you know how to mitigate this issue?

Kind regards, Thomas

For those struggling to reproduce (like me): Make sure to load the packages signal (for butter()) and mapping (for deg2rad()) in Octave 3.6.4. The top of the Script.m file thus has to look like this:

clear;
close all;
clc;
pkg load signal;
pkg load mapping;
addpath('Quaternions');
addpath('ximu_matlab_library');
