Question: Skipping NULL values


I am a first time user of Maple. I have an (m x n) array called 'arr' with missing values. For all non NULL values within the array I'd like to apply a function, called 'EigenvalueEquation'. My Ansatz is as follows:

map(EigenvalueEquation, arr)

It produces an error since one cannot execute a function with a NULL value as an input. How can I skip those entries within my array? I'd like to avoid looping over the entire array.

Any help is greatly appreciated.
