SuperLU is a general purpose library for the direct solution of large, sparse, nonsymmetric systems of linear equations on high performance machines. The library is written in C and is callable from either C or Fortran. The library routines will perf

分形维数作为科学研究的重要工具之一,它是描述自然界和非线性系统中不光滑和不规则几何体的有效工具,其 计算方法已经有多种,应用领域也是十分广泛。然而,各种方法各有不同,文中就此对常用分形维数计算方法进行了系统 的综合与研究,主要包括圆规法、明科斯基方法、变换方法、盒子计算方法、周长- 面积法、裂缝岛屿方法、分形布朗模型法, 对每种方法的含义和模型及相关的应用领域进行了阐述,并给出了其方法的计算机实现算法。-As one of science study tools ,fractal d

The GMRES method was developed by Yousef Saad and Martin H. Schultz in 1986.[1] GMRES is a generalization of the MINRES method developed by Chris Paige and Michael Saunders in 1975. GMRES also is a special case of the DIIS method developed by Peter P
