masked_invalid(a, copy=True)

This function is a shortcut to masked_where , with :None:None:`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 types), but accepts any array_like object.

Mask an array where invalid values occur (NaNs or infs).

See Also

masked_where

Mask where a condition is met.

Examples

This example is valid syntax, but we were not able to check execution
>>> import numpy.ma as ma
... a = np.arange(5, dtype=float)
... a[2] = np.NaN
... a[3] = np.PINF
... a array([ 0., 1., nan, inf, 4.])
This example is valid syntax, but we were not able to check execution
>>> ma.masked_invalid(a)
masked_array(data=[0.0, 1.0, --, --, 4.0],
             mask=[False, False,  True,  True, False],
       fill_value=1e+20)

Local connectivity graph

Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.

Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)

SVG is more flexible but power hungry; and does not scale well to 50 + nodes.

All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
