Understanding the Concepts

• Normal: The normal of a matrix represents its overall “magnitude” or size. It is calculated as the square root of the sum of the squares of each element in the matrix.

• Trace: In a square matrix, the trace is the sum of the elements on the main diagonal. It provides insights into the matrix’s “linearity.”

JavaScript provides us with ways to find a square matrix’s normal and trace. In linear algebra, the total number of entries on the principal diagonal is indicated by the trace, while the normal represents the size of the matrix overall. It is critical to understand these concepts in a variety of computational and mathematical applications.
