Correlation, unequal row size

I have two variables,

1. Sales
2. Satisfaction

Sales column is 55 rows long

Satisfaction column is 61 columns long

I want to do Kendall correlation between them

BUT Matlab say rows must be same length

How to solve this problem?

Maybe some kind of interpolation?

Thank you.
