Ary6[1..2,0..-1]

Ruby
1

At the following:
http://ruby.gfd-dennou.org/tutorial/gokuraku/index-e.html

Under “Index”, I want to ask about the following:

ary6 = NArray.sfloat(4,3).indgen!(1.02.0) # This line didn’t work

ary6[1…2,0…-1] # What is meant by this line? didn’t understand how
the output was formed

Thanks.

This is just another form of array slicing, see
class Array - RDoc Documentation for the details.
