✅ The identity matrix of size n is the n.n square matrix with ones on the main diagonal and zeros elsewhere. It has unique properties, for example when the identity matrix represents a geometric transformation, the object remains unchanged by the transformation. In other contexts, it is analogous to multiplying by the number 1. The identity matrix can also be written using the Kronecker delta notation. 📌Don't forget...Like/Share/Follow👆❤️ ✅Follow @math.magazine 🔥 for more !!... ✅Follow @math.
