Hi,

Thank you for your reply. I understand that the Newton-Raphson method is used in nonlinear analysis, but I am currently working on linear static analysis. I solved x=k\F in MATLAB, and while the tendency seems to somewhat match, the values differ significantly. Could you tell me why such discrepancies might occur?
