Construct a 4 × 3 matrix A = [a_{i j}] whose elements a_{i j} are given by a_{i j} = 2i + \( \dfrac{i}{j}\)

Accepted Answer

Given a_{i j} = i

Let A = [a_{i j}]_4×3

So, the elements in a 4 × 3 matrix are

a₁₁, a₁₂, a₁₃, a₂₁, a₂₂, a₂₃, a_31,a_32,a_33,a_41, a_42, a₄₃

a₁₁ = 1

a₁₂ = 1

a₁₃ = 1

a₂₁ = 2

a₂₂ = 2

a₂₃ = 2

a₃₁ = 3

a₃₂ = 3

a₃₃ = 3

a₄₁ = 4

a₄₂ = 4

a₄₃ = 4

Substituting these values in matrix A we get,
