`numpy.ma.core:compressed`

Signature

def compressed ( x )

Return all the non-masked data as a 1-D array.

This function is equivalent to calling the "compressed" method of a ma.MaskedArray, see ma.MaskedArray.compressed for details.

import numpy as np

Create an array with negative values masked:

import numpy as np
x = np.array([[1, -1, 0], [2, -1, 3], [7, 4, -1]])
masked_x = np.ma.masked_array(x, mask=x < 0)
masked_x

Compress the masked array into a 1-D array of non-masked values:

np.ma.compressed(masked_x)
