The phrase "idempotent matrix" is an algebraic term. It is defined as a matrix that equals itself when multiplied by itself.
By rule of matrix multiplication the number of rows in the first matrix must equal the number of rows in the second matrix. If A is an axb matrix and B is a cxd matrix, then a = d. Then if BA is defined, then c = b. This means that B is not necessarily mxn, but must be nxm.
The determinant function is only defined for an nxn (i.e. square) matrix. So by definition of the determinant it would not exist for a 2x3 matrix.

To find the original matrix of an inverted matrix, simply invert it again. Consider A^-1^-1 = A^1 = A
A Risk Assessment Matrix helps you identify how risky a certain action can be.
The trace of a 3 by 3 matrix A is defined as the summation of n=3;i=1;aii.
No. Matrix addition (or subtraction) is defined only for matrices of the same dimensions.
No. Matrix addition (or subtraction) is defined only for matrices of the same dimensions.
To find a unitary matrix, one must first square the matrix and then take the conjugate transpose of the result. If the conjugate transpose of the squared matrix is equal to the identity matrix, then the original matrix is unitary.
