where the Jacobian is evaluated for every iteration and takes the form \begin{aligned} \textbf{J}=\begin{bmatrix}-X_1^\beta & \cdots & -X_N^\beta \\ -X_1^\beta \log X_1^\beta & \cdots & -X_N^\beta \log X_N^\beta \end{bmatrix}. \end{aligned} (71) ...
Models for resident infectious diseases, like the SIRS model, may settle into an endemic state with constant numbers of susceptible (S), infected (I) and recovered (R) individuals, where recovered individuals attain a temporary immunity to reinfection. For many infectious pathogens, infection ...
The idea of the Quasi-Newton method is to update the approximation of the Jacobian matrix using the information from the function values and the change in the unknowns from the previous iteration. The method updates the Jacobian approximation using the Broyden-Fletch...

How to prove the linearity of a reflection system? Linear Transformation A transformation T from a vector space V(F) to the vector space W(F) is said to be linear if there exists the scalars a and b over the field F such that the transformation satisfy the rule T(au+bv)=aT(u)+bT...
Your ODE system is linear - thus you can determine its general solution having 7 free parameters. But incorporating of your boundary conditions leads to a linear system of equations where the coefficient matrix A is rank-deficient (rank 6 instead of rank ...
Solve the system \left\{\begin{matrix} u = x - y \\ v = 3x + y \end{matrix}\right. for x and y in terms of u and v. Then find the value of the Jacobian \frac{\partial(x,y)}{\partial(u,v)}. Find the i Determine the order of each differential equation and...
