Construct a `3xx3` matrix whose elements are given by `a_(ij)={{:((1)/(2)|2i-3j|","i!=j),(|2i-j|","i=j):}`

Explanation

To construct a \(3 \times 3\) matrix \(A\) whose elements are defined by the given conditions, we will follow these steps:

### Step 1: Define the Matrix Structure
Let the matrix \(A\) be represented as follows:
\[
A = \begin{bmatrix}
a_{11} & a_{12} & a_{13} \\
a_{21} & a_{22} & a_{23} \\
...
