Newton-Raphson is not the … Witryna6 lut 2015 · I was given a piece of Matlab code by a lecturer recently for a way to solve simultaneous equations using the Newton-Raphson method with a jacobian matrix (I've also left in his comments). However, although he's provided me with the basic code I cannot seem to get it working no matter how hard I try.
Witryna20 sie 2024 · You can either use a more sophisticated root finding method or you can decrease dx and increase the number of iterations. For instance you can use dx/1000 and 1.5 million maximum iterations. That will give you all the roots. For roots 1 and 4.0996 you will have to use a very close guess. The code works well for simple … Witryna4 paź 2016 · Learn more about newton-raphson method .
