The Nelder-Mead algorithm or simplex search algorithm, originally published in 1965 (Nelder and Mead, 1965), is one of the best known algorithms for multidimensional unconstrained optimization without derivatives. In parallel to this, the use of the Finite Volume method has grown: see, for instance, the worlks of V azquez Cend on [31] and Alcrudo and Garcia- This page has links to MATLAB code and documentation for the finite volume method solution to the one-dimensional convection equation. Newmark's method, (Newmark, 1959), allows the direct solution of a second-order differential equation or a system of second-order differential equations without the need for the transformation to a pair of simultaneous first-order differential equations.The method may be applied in various fields of engineering, in particular to dynamic response systems. Driven by the need to solve complicated problems in the fields of civil and aeronautical engineering, scientists in the USA and USSR developed ways to break continuous domains into manageable elements. For the matrix-free implementation, the coordinate consistent system, i.e., ndgrid, is more intuitive since the stencil is realized by subscripts. The first is uFVM, a three-dimensional unstructured pressure-based finite volume academic CFD code, implemented within Matlab.
