Definition Thedeterminantof a matrix is simply a useful tool. Like its name suggests, it 'determines' things. When doing matrix algebra, orlinear algebra, the determinant allows you to determine whether asystem of equationshas a unique solution. ...
The theory of determinants arose in connection with the problem of solving a system of first-degree algebraic equations (linear equations). In the most important case, when the number of equations equals the number of unknowns, such a system may be written in the form This system has a uniq...
Linear algebraThe usual definition of determinant is difficult to understand the idea why this definition is introduced. In this report, I will consider the nonsingularity of matrices and introduce the determinant as a necessary and sufficient condition of the nonsingularity of matrices under some ...
The determinant function can be defined by essentially two different methods. The advantage of the first definition—one which uses permutations—is t

. That definition has been derived by mathematicians who took the following steps: they found some simple properties that are satisfied by the volumes of linearly transformed regions (e.g., if a linear transformation doubles the upper and lower edge of a rectangle and leaves its left and right...

Definition 1 We define the precision matrix as the Bott–Duffin inverse of the covariance matrix, since by Remark 4, we have(42)M=Σ(X⊥)(−1).Also, we denote the likelihood function (39) (i.e., a normal distribution on X⊥, but constant along X) by(43)y|θ∼NX⊥−1(0,...
