Update vector values and return to the program

Hi all! I faced to the problem and can't solve it. Please anybody help me. It's very important for me...

I wrote a program, where I input t vector by ginput(n). Then my program calculate and construct a curve by the developed method (calculation part of the program).

MY PROBLEM IS: I want change values of the t vector and return to the calculation part of my program, in other words, I want to refresh my t vector each time. How to do this????

(I drag t vector points on the curve and fix it as a refreshed value).

Thanks in advance. Waiting forward for the answers!!!!

Best regards, Mane

Mane, not quite sure I understand. Do you want to read ginput's over and over again (with some calculations in between)? Something like

 button = 1;
 while sum(button) <=3   % read ginputs until a mouse right-button occurs
   [x,y,button] = ginput(3);
 end

[Mane]

First of all, thanks very much for your response!

No, I want to read ginput only the first time, after that will be going some calculation algorithm, and then over and over again I want to drag the points and to process my calculation program each time.

In other words, I want see the changes on the constructed curve by changing points' position (t vector values)...

What do you mean by "drag points"? Where from, where to?

Here is the curve, that is constructed by my program.

Here the 'Points' are my t vector. First time I read this vector by ginput(n). After that work my calculation algorithm and finally the curve is constructed.

Now I want to drag these 'Points' (change the values of t vector), and see my curve changes in this case. So I want to work my calculation program every time as I change position of any of these points.

Please give me the way to solve my problem. It's so important to me...
