用C写的抛物线程序，用比较简单的数学运算将效果提现出来，抛物线的颜色和弧度都可以修改。-C parabola written procedures, using relatively simple arithmetic will show results to mention, the color and parabolic arc can be amended.

使用Qt实现函数型与参数型的样条函数,函数型包括自由边界和抛物边界，参数型包括均匀参数化，弦长参数化，向心参数化-Using Qt to achieve function type and parameter type spline function, function type, including free boundary and parabolic boundary, parameter types, including uniform parameterization, chord l

利用Qt实现三次样条插值，主要实现函数型和参数型，函数型包括自由边界和抛物边界，参数型包括均匀参数化，弦长参数化和向心参数化-Use Qt to achieve cubic spline interpolation, the main function type and parameter type, function type, including free boundary and parabolic boundary, parameter types, including uniform
