Hello! Can someone please say why getCorrelationCoefficientsMatrix doesn’t give the values??

Hi @daiana,

It’s because it’s a 2D JArray with an untyped “Object”, you have to cast it to a Jarray_double.
If corr is the object returned by your line of code, this should print you the matrix:

from orekit import JArray_double
import numpy as np

for i_line in np.arange(0, len(corr)):
    line = JArray_double.cast_(corr[i_line])
    print(line)

Hope this helps,
Maxime
