definition of mask function

Dear matlab expert, I got this function

eof_maps = eof(A,'mask',mask);

where A is a 3D matrix e.g 5x3x6. In the documentation, it says only performs EOF analysis on the grid cells represented by ones in a logical mask whose dimensions correspond to dimensions 1 and 2 of A. So I need to replace the varargin 2 with 5*3?

The 'mask' input for a 5 x 3 x 6 array for that function should be a 5 x 3 logical array.
