The Journal of Computational Mathematics is an international journal covering numerical methods, analysis and applications. The journal publishes original research papers in all branches of modern computational mathematics such as linear and nonlinear algebra, numerical optimization, numerical approximations, computational geometry, computational statistics and probability, Monte Carlo methods, numerical methods for ordinary differential equations, integral equations and partial differential equations including both direct and inverse problems, and computational-mathematical problems in diverse fields of science and engineering. Papers containing new ideas, creative approaches and/or innovative applications as well as invited reviews are expected to appear regularly in the journal. A special feature of the Journal of Computational Mathematics is the publication of articles selected by the editors, and translated into English, from the Chinese-language journal Mathematica Numerica Sinica. This will be of great interest to many computational and applied mathematicians who up to now have been unable to easily obtain translated material on Chinese mathematical research.
