Hi All,

Have programmed in another system until now and am trying to shift to
Mathematica and facing some diffciulties

I would like to create a matrix, say a[ndiv] and would like to
initilize all the value to i^2 (or any other value). The size of the
matrix is not fixed.

The code I tried to use is:

ndiv = 5;
a = {};
For[i=1, i<=ndiv, i++,
a[[i]] = i*i;

This is producing the following error:
partw: Part 1 of {} does not exist and so on.

I understand that I am not creating a matrix of size 1*ndiv for the
data to be fed it.

So I tried using Table as follows:

a = Table[0,{1},{ndiv}] followed by the above For loop (when I wanted
to initialize the matrix with say i*i;

Hope some one can help me in doing the above operation
