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.
In the context of matrix algebra there are more operations that one can perform on a square matrix. For example you can talk about the inverse of a square matrix (or at least some square matrices) but not for non-square matrices.
A square matrix K is said to be idempotent if K2=K.So yes K is a square matrix
Square Matrix: When m=n (Here m=Rows and n=colums) are same is called square matrix. Ex. A=|Bij|
A rectangle containing numbers are called "matrix" (1 0 0 1) (3 4 8 0) is a 2 x 4 matrix a SQUARE containing numbers is a n x n matrix, or square matrix (1 0) (5 6) is a square matrix (1) is a square matrix
A rectangular (non-square) matrix.

The identity matrix, which is a square matrix with zeros everywhere except on the principal diagonal where they are all ones.
A square matrix K is said to be idempotent if K2=K.So yes K is a square matrix
An idempotent is a matrix whose square is itself. Specifically, A^{2}=A. For example the 2x2 matrix A= 1 1 0 0 is idempotent.
An idempotent is a matrix whose square is itself. Specifically, A^{2}=A. For example the 2x2 matrix A= 1 1 0 0 is idempotent.
The idempotent matrix is also called square root of a matrix. i.e.)A2=A
A Hadamard Matrix is a square matrix composed of 1 or -1. Using a square matrix system the hadamard matrix could be created
Square Matrix: When m=n (Here m=Rows and n=colums) are same is called square matrix. Ex. A=|Bij|
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.
No. A square matrix has an inverse if and only if its determinant is nonzero.
a square matrix that is equal to its transpose
