Identity Matrix
An identity matrix is a fundamental concept in mathematics, particularly in the realm of linear algebra. It is a square matrix that holds ones on its main diagonal and zeros elsewhere. Denoted typically as "I" or "Iₙ" where "n" represents the size of the matrix, it serves as the equivalent of the number one in matrix multiplication. This special matrix plays a crucial role in various mathematical operations, serving as a neutral element akin to how the number one behaves in regular arithmetic. Its properties make it a cornerstone in solving systems of equations, transformations, and other mathematical applications.
