A determinant is defined only for square matrices, so a 2x3 matrix does not have a determinant.Determinants are defined only for square matrices, so a 2x3 matrix does not have a determinant.
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 determine whether the matrix product ( AB ) is defined, you need to check the dimensions of the matrices ( A ) and ( B ). Specifically, if matrix ( A ) has dimensions ( m \times n ) and matrix ( B ) has dimensions ( p \times q ), the product ( AB ) is defined if and only if the number of columns in ( A ) (i.e., ( n )) is equal to the number of rows in ( B ) (i.e., ( p )). If this condition is met, the resulting matrix ( AB ) will have dimensions ( m \times q ).
To find the original matrix of an inverted matrix, simply invert it again. Consider A^-1^-1 = A^1 = A
No, a 3x5 matrix cannot be multiplied by another 3x5 matrix. For matrix multiplication to be possible, the number of columns in the first matrix must equal the number of rows in the second matrix. Since a 3x5 matrix has 5 columns and the second 3x5 matrix has 3 rows, multiplication is not defined in this case.
No. Matrix addition (or subtraction) is defined only for matrices of the same dimensions.

The trace of a 3 by 3 matrix A is defined as the summation of n=3;i=1;aii.
