Correlation between two variables (not same size, not pairs)

Hi, I'm new to Matlab and have a question.

I have these two variables, fi and fu.

fi has 94 rows and 1 column.

fu has 41 rows and 1 column.

How can I calculate the correlation between fi (as a whole) and fu (as a whole), and the P-value?

I don't want the correlation changes when I change the sort of numbers either in fi or in fu (like below).

.

row 1: fi(1) fu(1)

row 2: fi(2) fu(2)

------------------

row 1: fi(1) fu(2)

row 2: fi(2) fu(1)

.

any help would be appreciated
