![**Q6/ What's the output of eye(4)**
In this question, we are referring to the function `eye(4)`, which is commonly used in various programming languages, such as MATLAB or Python's NumPy, to generate an identity matrix of size 4x4. An identity matrix is a square matrix with ones on the diagonal and zeros elsewhere.
For `eye(4)` the output is as follows:
\[
\begin{bmatrix}
1 & 0 & 0 & 0 \\
0 & 1 & 0 & 0 \\
0 & 0 & 1 & 0 \\
0 & 0 & 0 & 1
\end{bmatrix}
\]
This is a 4x4 matrix, where all the diagonal elements (from the top left to the bottom right) are ones, and all the off-diagonal elements are zeros. This matrix is called the identity matrix because it acts as the multiplicative identity in matrix multiplication.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fcd32005b-cd45-489d-9c55-223ef01177bc%2Fdbba3dc1-ec8f-486f-a599-437a6bb8d5a6%2F2ndhjoq_processed.jpeg&w=3840&q=75)
