dask.array.ma.masked_outside

dask.array.ma.masked_outside(x, v1, v2)[source]

Mask an array outside a given interval.

This docstring was copied from numpy.ma.masked_outside.

Some inconsistencies with the Dask version may exist.

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.

See also

masked_where

Mask where a condition is met.

Notes

The array x is prefilled with its filling value.

Examples

>>> import numpy.ma as ma  
>>> x = [0.31, 1.2, 0.01, 0.2, -0.4, -1.1]  
>>> ma.masked_outside(x, -0.3, 0.3)  
masked_array(data=[--, --, 0.01, 0.2, --, --],
             mask=[ True,  True, False, False,  True,  True],
       fill_value=1e+20)

The order of v1 and v2 doesn’t matter.

>>> ma.masked_outside(x, 0.3, -0.3)  
masked_array(data=[--, --, 0.01, 0.2, --, --],
             mask=[ True,  True, False, False,  True,  True],
       fill_value=1e+20)
