Method: Daru::Vector#type

Defined in:
lib/daru/vector.rb

#type ⇒ Object

The type of data contained in the vector. Can be :object or :numeric. If the underlying dtype is an NMatrix, this method will return the data type of the NMatrix object.

Running through the data to figure out the kind of data is delayed to the last possible moment.
