verde.base.n_1d_arrays¶

verde.base.n_1d_arrays(arrays, n)[source]¶

Get the first n elements from a tuple/list, convert to arrays, and ravel.

Use this function to make sure that coordinate and data arrays are ready for building Jacobian matrices and least-squares fitting.

Parameters

arrays (tuple of arrays) – The arrays. Can be lists or anything that can be converted to a numpy array (including numpy arrays).
n (int) – How many arrays to return.

Returns

1darrays (tuple of arrays) – The converted 1D numpy arrays.

Examples

>>> import numpy as np
>>> arrays = [np.arange(4).reshape(2, 2)]*3
>>> n_1d_arrays(arrays, n=2)
(array([0, 1, 2, 3]), array([0, 1, 2, 3]))
