RS Type 3 â This type of resistant starch is the result of a process called retrogradation-when starches are cooked and then immediately cooled, which allows the digestible starch in some foods like rice, potatoes, and beans to be more resistant to digestion.
Determinants are simple, the eigenvalues are just the diagonal entries and the eigenvectors are just elements of the standard basis. Even the inverse is a piece of cake (if the matrix is nonsingular). Although most matrices are not diagonal, many are diagonalizable, that is they are similar to a diagonal matrix. Definition. A matrix A is diagonalizable if A is similar to a diagonal matrix D.
Properties. Sums and scalar products of skew-symmetric matrices are again skew-symmetric. Hence, the skew-symmetric matrices form a vector space. If matrices A and B are both skew-symmetric, then their product AB is a symmetric matrix. On the other hand, the triple product B AB is skew-symmetric.f A is skew-symmetric and x is vector then x Ax = 0. All main diagonal entries of a skew-symmetric matrix have to be zero, and so the trace is zero.
