@Markiyan Hirnyk  Sorry I bothered you, now I got your point. Thanks again.

Thanks for replying Mehdi Jafari. These equations work for me!

Thanks for replying Markiyan.

I tried 

> e := Matrix([0.1e-2, 0.5e-1, .151, .201, .301, .951, 2]):
s := kronecker([e], Matrix(1, 12, 1));

But, i am getting this error:

Error, (in numtheory:-kronecker) wrong number of arguments

About equation 'a'

I just want to get an output like this in Maple

a= [ 1, 1.5, 2, 2.5, 3, 3.5, ................. , 149.5, 150]

It takes alot of time to input these values, so i want to simplify it

@acer Thankyou for sharing these links :)

@acer Thanks for the revised version for Maple 12! Its working now. Yes, your function 'f' is really helpful for interpolation. Its okay, and yes you are right i have discrete regular grid of x-y points and their corresponding z values and I want to interpolate it further to get a smooth curve. Sorry for not being clear in my last post.  

Now from interpolation graphs, I further want to create a polynomial equation for curve fitting. How to fit 3D plot in polynomial? Sorry for bothering you

Thanks for replying acer! Well, I have just added a small portion of my data to understand this concept. My original data is extremely large and it has too many values. I want to create a polynomial for the curve fitting of my 3D plot.

Anyways, I execute your first code but I am getting this error.

Error, (in plot3d/options3d) expecting option orientation to be of type [realcons, realcons] but received [-111, 83, -14]

I am not able to plot the graph. Actually I’m working on an old version of Maple ( Maple 12). Maybe I am not able to load your full code. Even your function ‘f’ is not working for me. I am getting this error.

Warning, unable to evaluate the function to numeric values in the region; see the plotting command's help page to ensure the calling sequence is correct

What does it meant by realcons? How did you set the orientation?

Can we use curvefitting from tools option (Assistant).  Can “PolynomialInterpolation” and “Interactive” commands be used? 

Thanks once again
