Coefficient matrix of linear equations from finite element method (FEM) is sparse and symmetrical. For the sake of CPU operational time saving to accesses data in matrix decomposition and reducing ...

Hermite approximation in multiple dimensions is investigated. As an example, a spectral scheme and a pseudospectral scheme for the Logistic equation are constructed, respectively. The stability and ...

All intuitionistic fuzzy TOPSIS methods contain two key elements: (1) the order structure, which can affect the choices of positive and negative ideal-points, and construction of admissible ...
