Its product suite reflects the philosophy that given great tools, people can do great things. The symamd function may also work well for symmetric indefinite matrices. The approximate minimum degree algorithm generates an ordering based on how these degrees are. In numerical analysis the minimum degree algorithm is an algorithm used to permute the rows and columns of a symmetric sparse matrix before applying the cholesky decomposition, to reduce the number of nonzeros in the cholesky factor. This matlab function returns the column approximate minimum degree.
