WebJun 10, 2024 · Learn more about differential equations, solving analytically, homework MATLAB I have a fluid dynamics problem and I need to derive an equation for motion. After applying Newtons second law to the system, and replaceing all the constants with A and B. WebIn Matlab we can solve this problem using the normal equations A⊤Ac =A⊤y and use M = A’*A; b = A’*y; c = M\b There is a Matlab shortcut for this: We can just type c=A\y(as if we were solving the linear system Ac =y). On a computer with machine arithmetic it turns out that solving the normal equations can be a numerically unstable algorithm.
