Regular matrix
Given a square matrix
, if a matrix 
satisfying 
exists, 
is denominated as a regular matrix, and 
its inverse matrix.
determinant resulting from the elements of 
Matrix of cofactors
Consider that the matrix
is regular. we have
The matrix
is the denominated matrix of cofactors of
.Transposed matrix
The matrix obtained by exchanging the rows with the columns of matrix
is called a transposed matrix and is represented by:
The matrix obtained by replacing all elements of
by their complex conjugates is denoted
