利用最小二乘法进行曲线的拟合,这是用多项式拟合曲线的源码!...

程序：全主元Gauss消去法 过程：gaussq(aa,bb,xx,n,sgn) 作用：aa为系数矩阵，bb为右端向量，xx为解向量，n为方程阶数，sgn为标识符，1表示计算正常进行，0表示计算失败 方程形式为：aa(n,n)*x(n)=bb(n)-Procedure: All the main element Gauss elimination process: gaussq (aa, bb, xx, n, sgn) Role: aa for the coefficient matrix, bb for the right-hand side vector, xx for the solution vector, n the order of the equation, sgn as identifiers, 1 indicates the calculation as normal, 0 indicates failure of the calculation equation of the form: aa (n, n)* x (n) = bb (n)
