Vector, 1D{2} dataset
---------------------
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.
.. code-block:: default
import csdmpy as cp
filename = "https://osu.box.com/shared/static/w63851uqruzhz6kx9rx5qgk3or2pot9l.csdf"
vector_data = cp.load(filename)
print(vector_data.data_structure)
.. rst-class:: sphx-glr-script-out

.. code-block:: none
{
"csdm": {
"version": "1.0",
"read_only": true,
"timestamp": "2019-02-12T10:00:00Z",
"dimensions": [
{
"type": "linear",
"count": 10,
"increment": "1.0 m",
"quantity_name": "length",
"reciprocal": {
"quantity_name": "wavenumber"
}
}
],
"dependent_variables": [
{
"type": "internal",
"numeric_type": "float32",
"quantity_type": "vector_2",
"components": [
[
"0.6907923, 0.31292602, ..., 0.40570852, 0.7005596"
],
[
"0.5603441, 0.06866818, ..., 0.48200375, 0.15077808"
]
]
}
]
}
}
The tuple of the dimension and dependent variable instances from this example
are
.. code-block:: default
x = vector_data.dimensions
y = vector_data.dependent_variables
with coordinates
.. code-block:: default
print(x[0].coordinates)
.. rst-class:: sphx-glr-script-out
Out:
.. code-block:: none
[0. 1. 2. 3. 4. 5. 6. 7. 8. 9.] m
In this example, the components of the dependent variable are
vectors as seen from the
:attr:`~csdmpy.DependentVariable.quantity_type`
attribute of the corresponding dependent variable instance.
.. code-block:: default
print(y[0].quantity_type)
.. rst-class:: sphx-glr-script-out
Out:
.. code-block:: none
vector_2
From the value `vector_2`, `vector` indicates a vector dataset, while `2`
indicates the number of vector components.
**Visualizing the dataset**
