def []( *args )
  target = Node.fit args
  if target.dimension == 0
    target = Hornetseye::MultiArray target, 1
  elsif target.dimension > 1
    target = Hornetseye::MultiArray OBJECT, 1
  end
  target[*args]
end

.import(typecode, string, size) ⇒ Node

Import array from string

Create an array from raw data provided as a string.

Parameters:

  • typecode (Class) —

    Type of the elements in the string.

  • string (String) —

    String with raw data.

  • size (Integer) —

    Size of array.
