Defined in:
lib/nmatrix/enumerate.rb

#each_layer(get_by = :reference) ⇒ Object

call-seq:

each_layer -> { |column| block } -> ...

Iterate through each layer, referencing it as an NMatrix slice.

Note: If you have a 3-dimensional matrix, the first dimension contains rows, the second contains columns, and the third contains layers.
