曲线拟合-Curve Fitting

通过C语言编程实现数值计算方法中的雅可比迭代，输入各个方程组的系数和迭代次数可以得到方程的精确解和中间计算结果。另外方程组未知数的个数可以自行设定。-Through the C language programming to achieve numerical method of Jacobi iteration, enter all equations of the coefficients and number of iterations can be exact solutions of equations and intermediate results. Another unknown number of equations can be set.
