Vector, 1D{2} dataset
---------------------

.. GENERATED FROM PYTHON SOURCE LINES 6-12

The 1D{2} datasets are one-dimensional, :math:`d=1`, with two-component
dependent variable, :math:`p=2`. Such datasets are more common with the
weather forecast, such as the wind velocity predicting at a location
as a function of time.

The following is an example of a simulated 1D vector field dataset.

attribute of the corresponding dependent variable instance.

    vector_2




.. GENERATED FROM PYTHON SOURCE LINES 38-40

From the value `vector_2`, `vector` indicates a vector dataset, while `2`
indicates the number of vector components.
