Numpy MaskedArray.ravel() function | Python
numpy.MaskedArray.ravel() function is used to return a 1D version of self mask array, as a view.
order : [‘C’, ‘F’, ‘A’, ‘K’, optional] By default, ‘C’ index order is used.
–> The elements of a are read using this index order.
–> ‘C’ means to index the elements in C-like order, with the last axis index changing fastest, back to the first axis index changing slowest.
–> ‘F’ means to index the elements in Fortran-like index order, with the first index changing fastest, and the last index changing slowest.
–> ‘A’ means to read the elements in Fortran-like index order if m is Fortran contiguous in memory, C-like order otherwise.
–> ‘K’ means to read the elements in the order they occur in memory, except for reversing the data when strides are negative.
Return : [ MaskedArray] Flattened 1D masked array.
Code #1 :
Input array : [[ 1 2] [ 3 -1]] Masked array : [[1 --] [-- -1]] 1D view of masked array : [1 -- -- -1]
Code #2 :
Input array : [[[ 2.0e+08 3.0e-05]] [[-4.5e+01 2.0e+05]]] 3D Masked array : [[[-- 3e-05]] [[-45.0 200000.0]]] 1D view of masked array : [-- 3e-05 -45.0 200000.0]
