Construct a `3 xx 4`matrix, whose elements are given by:(i) `a_(i j)=1/2|-3i+j|` (ii) `a_(i j)=2i-j`

Explanation

To construct the required \(3 \times 4\) matrices based on the given definitions, we will follow these steps:

### Part (i): Constructing the matrix using \(a_{ij} = \frac{1}{2} |-3i + j|\)

1. **Define the matrix dimensions**: We need a \(3 \times 4\) matrix, which means we will have 3 rows and 4 columns.

2. **Calculate each element**:
- For \(i = 1\):
