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.
haw can draw?

we will take the three points from the keyboard then we will draw a parabola which intercepts these points so we need a method to solve this problem.

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.

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).

This does not answer the OP's question.
