How to convert a matrix of complex cartesian values into a matrix of polar values?

I'm trying to convert a matrix of complex cartesian values into a matrix of complex polar values.

So far I've tried the absolute function, but it's only giving me a single polar value, instead of a matrix of multiple polar values.

I've had a look through the Quicksheets already but could'nt find what I was looking for.

Any help would be greatly appreciated
