I have attached intensity graph which is obtained from edge detection function. Its a 2d array of numeric data. I wanted to do a curve fit for this data. Can anybody help me.
First thing you have to have a clue about is the curve form. Is it a cylindric/circle form or a sine or else. Then you choose the proper fiting function in Mathematics > Fitting.
I assume it is a cylindrical form, so I would go with the "Nonlinear curve fit" and implement a formula string for z=z(x,y).
hey thanks for your reply, plz find the intensity graph data attached to the post. i am supposed to do fitting for this. I guess parabolic fitting will do for this. How should i go about it?
