Positive Definite Matrix A simpler way to define if a matrix is positive definite it is, a matrix is positive definite if it's symmetric and all its eigenvalues are positive. We can also define it in terms of pivots. Another definition uses its quadratic form, which is A matrix A is pos...
A square matrix is positive definite if pre-multiplying and post-multiplying it by the same vector always gives a positive number as a result, independently of how we choose the vector. Positive definite symmetric matrices have the property that all their eigenvalues are positive. ...

Definite Stuff One of my favorite uses for symmetric matrices (where B = C) is to represent homogeneous polynomials: (5.7)[xy]ABBDxy=Ax2+2Bxy+Dy2 If this expression has no real roots, that is, it's positive (or negative) for all [xy], the matrix is called positive (negative) defi...
