关于BP网络的设计及改进方案实现分类，包含matlab源程序(On the BP network to achieve improvement program design and classification, including source code matlab)

设计低通数字滤波器，要求在通带内频率低于 时，允许幅度误差在1dB以内，(Design of digital low pass filter, requirements in the passband frequencies below, allow a margin of error of less than 1dB,)

％ 用途：选列主元Gauss消去法解线性方程组ax=b ％ 格式：x=nagauss2(a,b,flag) a为系数矩阵，b为右端列向量，flag若为0，则显示中间过程 ％ 否则不显示，默认值为0，x为解向量 ( Usage: Selected Principal Gauss elimination method solution of linear equations ax = b format: x = nagauss2 (a, b, flag) a for the coefficient matrix, b for the right side column vector, flag if it is 0, it shows the middle Otherwise, the process does not appear, the default value is 0, x for the solution vectors)
