My … Some very short and noisy time series (~5 observations of half missed clouds/shadows, unmasked -9999s, etc) created 0 weighted observations, causing the median … That means its determinant is equal to zero. When you multiply A with B the resulting matrix is also singular and then you multiply by C to get E. That means that E is also singular (if you multiply two matrices and at least one of them is singular the result is always singular). The language barrier is hitting me hard. So, in the above image, you can see that the interpreter threw a LinAlgError: Singular matrix. The inv function could also be improved, but it only fails if the matrix is numerically singular, which is a different thing from exact singularity. import numpy as np import matplotlib.pyplot as plt nvec = np.array ( [3, 10, 20, 50]) # n intervals as given in the problem xL = 1; xR = 4; #left and right bounds def f (x): return np.sin … I'm trying to carry out one dimensional kriging using the python module 'pykrige' but I'm getting a few errors. scipy.linalg.solve(a, b, sym_pos=False, lower=False, overwrite_a=False, overwrite_b=False, debug=None, check_finite=True, assume_a='gen', transposed=False) [source] #.
