draw parabola
显示 更早的评论
Write a Matlab m-file to input three points (x1,y1), (x2,y2) and (x3,y3) in the x-y plane, and to draw the function and output the equation of a parabola passing through these points.

So? This is not the we do your homework site. Sean has already given you some hints to get started. Why not make a stab at it? If you have a problem with something, THEN ask a question.

Hello, you improve your question.
Your question would be:
1). Write a program in Matlab, to find the equation of the parabola with focal axis parallel to the X axis passing through the points (x1, y1), (x2, y2) and (x3, y3).
2). Write a program in Matlab, to find the equation of the parabola with focal axis parallel to the Y axis, passing through the points (x1, y1), (x2, y2) and (x3, y3).
3). Write a program in Matlab, to find the equation of the parabola passing through the points (x1, y1), (x2, y2) (x3, y3), (x4, y4) and (x5, y5).
