A square matrix K is said to be idempotent if K2=K.So yes K is a square matrix
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 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
Yes.
A rectangular (non-square) matrix.

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
No. A square matrix has an inverse if and only if its determinant is nonzero.
a square matrix that is equal to its transpose
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
Involtary Matrix A square matrix A such that A2=I or (A+I)(A-I)=0, A is called involtary matrix.
To square a matrix, simply multiply the matrix by itself. It is just like squaring any other regular number in mathematics.
Yes.
A rectangular (non-square) matrix.
A skew symmetric matrix is a square matrix which satisfy, Aij=-Aji or A=-At
