Correlation matrix analysis between groups. Need help.

Hi everbody.
I'm in trouble for my data analysis and i need some help.
I have one correlation matrix (same label variables and size) for each one of my 22 subject.
The aim of my study is comparing the strength of each correlation in correlation matrix between two groups (9 subjects vs 13 subjects).
So is it possible in some way building an "average matrix" from the correlation matrix of 9 subjects and an other one for the remaning 13 subject and then comparing the two "averaged matrices"

Thank a lot to everyone
