LUDCMP

代码说明：

  程序名为LU分解法。功能：求解系数矩阵为非奇异的线性代数方程组Ax=b，它能串联式地逐次解A相同b不同的方程组。本方法将高斯主元消去法中的中间结果的记录次数从约n^3/3次减少到约n^2次。子过程LUDCMP将系数矩阵A分解为上三角矩阵和下三角矩阵。子过程LUBKSB利用LUDCMP的分解结果求得线性方程组Ax=b的解。(Program called LU decomposition. Function: non-singular coefficient matrix solving linear algebraic equations Ax = b, it tandem to the same b successive solution A different equations. The method of the Gaussian elimination method master record of the results of the intermediate frequency from about n ^ 3/3 was reduced to about n ^ 2 times. Sub-process LUDCMP the coefficient matrix A is decomposed into upper triangular matrix and lower triangular matrices. Sub-process LUBKSB decomposition results obtained using the LUDCMP linear equations Ax = b solution.)
