Thank you.

Thanks very much.This will help.But I needed a definition with respect to kronicker delta function or some combinition of it,the definition of this function is:

                                                  f(i,j)=0 if i≠j & 1 if i=j.

As you can see it directly gives the elements of a general NbyN identity matrix.Now,my question is how I have to modify this function or combine(add,subtraction or multiply) it with itself to get the elements of a shift matrix?

f(i+1,j) will not do,because it fails to give the last row,similar problem arises if I try f((j+1) mod (N+1),j).

Is there a general formula at all?

After getting the formula,I have to write a Maple code using this formula to generate a upper shift matrix which takes the dimension(N) of the matrix as input.

You see my problem?I can't use the built-in facilities of Maple,while using Maple.

I forgot to mention the debugging issue.A compiled program is obviously difficult to debug,imagine a program written in a HLL with thousand or more lines in it,but you don't have the advantage of line by line compilation like a CAS(to be honest,this slows down the runtime,but I mentioned my points on runtime issue above).

But I still have a question.

If my procedure doesn't take symbolic argument,then it should show this behaviour everywhere(am I right ?).

But in the for loop,that I wrote to print the numerical values,my procedure 'zcor' takes a symbolic argument 'f' & it works.

It  seems that , it  doesn't work inside the 'plot' function only.

What is the reason?

Thanks.

I used Newton's laws of motion directily,so integration wasn't needed.
