Hi,
would like to take eliminate a specific number in an array and its
correspondent in an other array, and vice-versa.
given
a=np.array([1,2,4,4,5,4,1,4,1,1,2,4])
b=np.array([1,2,3,5,4,4,1,3,2,1,3,4])
no_data_a=1

As I discovered when running the solution before, your test data are
wrong, leaving out 2,3 before the last pair (4,4). Anyway, for those
interested in a plain Python solution, without numpy:
a=[1,2,4,4,5,4,1,4,1,1,2,4]
b=[1,2,3,5,4,4,1,3,2,1,3,4]
no_data_a=1
no_data_b=2
a_clean=(4,4,5,4,4,2,4)
b_clean=(3,5,4,4,3,3,4)
cleaned = list(zip(*(pair for pair in zip(a,b)
if pair[0] != no_data_a and pair[1] != no_data_b)))
print(cleaned, cleaned == [a_clean, b_clean])
#
[(4, 4, 5, 4, 4, 2, 4), (3, 5, 4, 4, 3, 3, 4)] True
