The idempotent matrix is also called square root of a matrix. i.e.)A2=A
matrix
A square matrix K is said to be idempotent if K2=K.So yes K is a square matrix
The diagonal terms give the variances. The square root of which gives the standard deviations. The diagonal terms give the variances. The square root of which gives the standard deviations.
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 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|
The square root of the square root of 2
No. A square matrix has an inverse if and only if its determinant is nonzero.

There are infinitely many of them. They include square root of (4.41) square root of (4.42) square root of (4.43) square root of (4.44) square root of (4.45) square root of (5.3) square root of (5.762) square root of (6) square root of (6.1) square root of (6.2)
It's not a square if it has no root. If a number is a square then, by definition, it MUST have a square root. If it did not it would not be a square.
a square matrix that is equal to its transpose
