Newton’s method is a special mathematical technique … Witryna17 gru 2024 · In this answer, I recommended using mpmath Python library for arbitrary precision.. Notice, that since matrices in mpmath are implemented as dictionaries:. Only non-zero values are stored, so it is cheap to represent sparse matrices. thus, this particular library seems like a good fit for your purpose of debugging.

WitrynaIf \(x_0\) is close to \(x_r\), then it can be proven that, in general, the Newton-Raphson method converges to \(x_r\) much faster than the bisection method. However since \(x_r\) is initially unknown, there is no way to know if the initial guess is close enough to the root to get this behavior unless some special information about the function is …
