Performing a factorial repeated measures ANOVA

Hi,
I have the following data and would like clarity on the correct MATLAB function to use.
I have n amount of participants in one single group.
These n people perform 6 different tasks.
I have 3 dependent measurements (metric 1, metric 2, metric 3) for which I want to see if each metric various across the 6 different tasks.
I do not want to analyse the differences in metric 1, 2 and 3). I.e. each metric can be statistically analysed seperately to each other.
Thanks in advance.

I understand that you are seeking clarification on the appropriate MATLAB function to analyse the metric variation across the tasks.
This can be done using a Repeated Measures ANOVA test, i.e., a test for the differences in variance across matched samples in multiple groups of data. Here the groups are the tasks, and the matching is between the participants (i.e., the groups are not comprised of independent data, so a normal ANOVA test is insufficient). You should perform one of these for each metric.
Here is the MATLAB documentation for that:
