Instance Method Summary

• #dimensions(n = 0) ⇒ Object

  Defines the number of dimensions: [1,2,3] is 1-dimensional [[1,2,3], [1,2,3]] is 2-dimensional [[[1,2,3], [1,2,3]], [[1,2,3], [1,2,3], [[1,2,3], [1,2,3]]]] is 3-dimensional So [[[1,2,3], [1,2,3]], [[1,2,3], [1,2,3], [[1,2,3], [1,2,3]]]].dimensions == 3.

Instance Method Details

#dimensions(n = 0) ⇒ Object

Defines the number of dimensions:

1,2,3

is 1-dimensional

[1,2,3], [1,2,3]

is 2-dimensional

[[1,2,3], [1,2,3]], [[1,2,3], [1,2,3], [[1,2,3], [1,2,3]]]

is 3-dimensional

So [[[1,2,3], [1,2,3]], [[1,2,3], [1,2,3], [[1,2,3], [1,2,3]]]].dimensions == 3
