A square matrix is a matrix with the same number of rows and columns, meaning it has a size of ( n \times n ). For example, the following is a ( 2 \times 2 ) square matrix:

[ \begin{pmatrix} 1 & 2 \ 3 & 4 \end{pmatrix} ]

Square matrices play a crucial role in various mathematical concepts, including determinants, eigenvalues, and linear transformations.

What is idompotent matrix?

An idempotent matrix is a square matrix ( A ) that satisfies the condition ( A^2 = A ). This means that when the matrix is multiplied by itself, it yields the same matrix. Idempotent matrices are significant in various areas of linear algebra and statistics, particularly in projection operations. An example of an idempotent matrix is the zero matrix, as well as any projection matrix onto a subspace.


Does every square matrix have an inverse?
