larray.larray_nan_equal

larray.larray_nan_equal(a1, a2)

Compares two arrays and returns True if they have the same axes and elements, False otherwise.

Parameters:

a1, a2 : LArray-like

Input arrays. aslarray() is used on non-LArray inputs.

Returns:

bool

Returns True if the arrays are equal, even in the presence of nan values (if they are at the same positions).

Examples

>>> arr1 = ndtest((2, 3), dtype=float)
>>> arr1['a1', 'b1'] = nan
>>> arr1
a\b   b0   b1   b2
 a0  0.0  1.0  2.0
 a1  3.0  nan  5.0
>>> arr2 = arr1.copy()
>>> larray_equal(arr1, arr2)
False
>>> larray_nan_equal(arr1, arr2)
True
>>> arr2['b1'] = 0.0
>>> larray_nan_equal(arr1, arr2)
False
>>> arr3 = arr1.set_labels(X.a, ['x0', 'x1'])
>>> larray_nan_equal(arr1, arr3)
False
>>> larray_nan_equal([0], [0])
True
