Explicit and implicit methods are approaches used in numerical analysis for obtaining numerical solutions of time-dependent ordinary and partial differential equations, as is required in computer simulations of physical processes. Explicit methods calculate the state of a system at a later time from the...
简单理解,就是把非线性的关系,用无数段微元给准确表达出来;毕竟,绝大多数非线性关系都是无法通过一个函数表达式来直接描述的,因此计算机只能将这条曲线分为无数段微元,在每个微元内按固定的法则进行计算。此时用到的法则,就可以分为显示(Explicit)与隐式(Implicit)两大类型。 (线性问题当然不需要考虑这些。因为...

Explicit and Implicit methods are used in numerical simulations to solve a physical process or a series of changes. You may apply these to many scientific simulations that involve time changes such as big bang, chemical reactions, fusion, even social science models. In mathematical terms, they ...
If f(u) = Au where A is a matrix independent of u then the implicit scheme requires solving the system of equations (I-hA).u(n+1) = u(n) and so a matrix inversion needs to be performed. The main pros and cons of these two methods are that explicit schemes are easy to program...
prove that the implicit method satisfies the charge conservation law exactly.Both methods provide accurate solutions in long-time computations and simulate the soliton collision well.The numerical results show the abilities of the two methods in preserving the charge,energy,and momentum conservation laws...
In contrast, FL and L2 teaching methods like "Audiolingualism ," which held sway during World War II, and more recent "Natural" and "Communicative" approaches, maintained that adult language learning is, like L1 acquisition , implicit. Since language skill is very different from knowledge about...
extracted from a single sequential program. These implicit threads may be defined either statically by the compiler or dynamically by the hardware. In the remainder of this section we consider explicit multithreading. 2 The term context switch is often found in OS literature and textbooks. Unfortunat...
Learn how to define custom implicit and explicit type conversions in C#. The operators provide the functionality for casting an object to a new type.
