The image contains a question and instructions for an assignment labeled "OPH-01." Here is the relevant information extracted from the image:

Question:

Describe the differences between scalar matrices and diagonal matrices, using an example.

Rules:

1. Must be handwritten.
2. Size: A4, one side.
3. Top of the A4 paper:
   • OPH = {1, 0, 1, 2}; OPH-01
   • First name + Family name + Student number
4. Deadline: First day at OHEUM.

Would you like me to explain the differences between scalar matrices and diagonal matrices with examples, or provide any additional help regarding the assignment? Here are five related questions for further understanding:

1. What are some common properties of diagonal matrices?
2. Can every scalar matrix be considered a diagonal matrix? Why or why not?
3. What are some real-life applications of diagonal matrices and scalar matrices?
4. How do scalar matrices behave under matrix multiplication with other matrices?
5. Can a diagonal matrix have zero elements on the diagonal?

Tip: When writing out matrices, it’s helpful to carefully label your rows and columns for clarity.
