Dear all,
I have a matrix with dimension of (360,720) but with all global data.
I have another land-sea mask matrix with only 2 unique values in it
(land=1, sea=-1).
So I can easily create transform the second array to a masked array.
the problem is, how can I quickly transform the first one to a masked array
using the same mask as the land-sea mask array?
I hope my question is clear. If not, here is an example:
In [93]: a=np.arange(10).reshape(2,5)
In [95]: a=np.ma.masked_equal(a,2
In [96]: a=np.ma.masked_equal(a,8)
In [97]: a
Out[97]:
masked_array(data =
[[0 1 -- 3 4]
[5 6 7 -- 9]],
mask =
[[False False True False False]
[False False False True False]],
fill_value = 8)
In [100]: b=np.random.normal(0,2,size=(2,5))
I want to convert b to a masked array using exactly the same mask as a.
thanks to all,
cheers,
Chao
