What is the physical significance of rank of matrix?
Can you give me an example of how rank can be used in a real-world context?
Sure! In engineering, the rank of a matrix can be used to determine the number of independent equations in a system of linear equations or to determine if a system is solvable. In finance, the rank of a correlation matrix can provide information on the relationships between various assets in a portfolio. And in image processing, the rank of a matrix can be used to determine the number of independent features in an image, which can be further analyzed for pattern recognition or compression purposes.
