To suppress whole columns of a 2-D array that contain masked values, use the np.ma.mask_compress_cols() method in Numpy. A masked array is the combination of a standard numpy.ndarray and a mask. A mask is either nomask, indicating that no value of the associated array is invalid, or an array of ... Read More

To mask an array where a condition is met, use the numpy.ma.masked_where() method in Python Numpy. Return the array to mask as an array masked where condition is True. Any masked values of a or condition are also masked in the output.The condition parameter sets the masking condition. When condition ... Read More

To mask using floating point equality, use the numpy.ma.masked_values() method in Python Numpy. Return a MaskedArray, masked where the data in array x are approximately equal to value, determined using isclose. The default tolerances for masked_values are the same as those for isclose.A masked array is the combination of a ... Read More

To mask an array outside a given interval, use the numpy.ma.masked_outside() method in Python Numpy. Shortcut to masked_where, where condition is True for x outside the interval [v1, v2] (x < v1)|(x > v2). The boundaries v1 and v2 can be given in either order.A masked array is the combination ...

To mask an array where the data is exactly equal to value, use the numpy.ma.masked_object() method in Python Numpy. This function is similar to masked_values, but only suitable for object arrays: for floating point, use masked_values instead.A masked array is the combination of a standard numpy.ndarray and a mask. A ... Read More

To mask an array where not equal to a given value, use the numpy.ma.masked_not_equal() method in Python Numpy. This function is a shortcut to masked_where, with condition = (x != value).A masked array is the combination of a standard numpy.ndarray and a mask. A mask is either nomask, indicating that ... Read More

To mask an array where invalid values occur (NaNs or infs), use the numpy.ma.masked_invalid() method in Python Numpy. This function is a shortcut to masked_where, with condition = ~(np.isfinite(a)). Any pre-existing mask is conserved. Only applies to arrays with a dtype where NaNs or infs make sense (i.e. floating point ... Read More

To mask an array inside a given interval, use the numpy.ma.masked_inside() method in Python Numpy. Shortcut to masked_where, where condition is True for x inside the interval [v1,v2] (v1

To return the default fill value for an array with float datatype, use the ma.default_fill_value() method in Python Numpy. The default filling value depends on the datatype of the input array or the type of the input scalar −datatypedefaultboolTrueint999999float1.e20complex1.e20+0jobject'?'string'N/A'For structured types, a structured scalar is returned, with each field the ...
