Actually, rather than focusing on the problem and the line of codes, i want to know about the difference between %ul and %lu How do you write matlab code for lu factorization when u is the unit matrix instead of l Maybe i could figure out what's wrong

Searching doesn't give me something useful (except that they are different)
Any explanation or link/reference is appreciated.
9 what is the difference between %zu and %lu in string formatting in c %lu is used for unsigned long values and %zu is used for size_t values, but in practice, size_t is just an unsigned long Cppcheck complains about it, but both work for both types in my experience.

Lu decomposition without pivoting is rarely seen in practice It's primarily used to introduced people to the idea of the technique, then the introduction builds by introducing pivoting. I understand that %zd is the suggested way to format the sizeof result However, i don't understand why that is necessary
For example using lu gives me the same output, and isn't the result of siz.
Lu decomposition error using sarimax in statsmodels asked 5 years, 3 months ago modified 3 years, 5 months ago viewed 4k times Conventional wisdom states that if you are solving ax = b several times with the same a and a different b, you should be using an lu factorization for lu If i use p, l, u = scipy.linalg.lu(a) and. I know there is a very similar question and answer on stackoverflow (here), but this seems to be distinctly different
I am using statsmodels v 0.13.2, and i am using an arima model as opposed to a
