What does this mean?

When I execute this formula on two matrices, what does this give me?
Where abs mean absolute value of numeric data.
mean(abs(a-b))/mean(abs(a))

The matrices would look like this figure below, but instead of letter there are counted values of how often something occurs:

A and B would be counted values, the values inside the matrix look like data that can be applied on a Fisher extract test.

And is this a linear algebra formula (what kind of math is this formula?)
