Find the 4x4 Identity Matrix 4

Problem

(I_4)

Solution

1. Identify the definition of an identity matrix, which is a square matrix with ones on the main diagonal and zeros elsewhere.

2. Determine the dimensions of the matrix, which is specified as 4×4

3. Construct the matrix by placing a 1 at each position (a_i*j) where i=j and a 0 where i≠j

Final Answer

(I_4)=([1,0,0,0],[0,1,0,0],[0,0,1,0],[0,0,0,1])
