... -0.4082R=1000-1 0002 The eigenvector in the first column of U corresponds to the eigenvaluein the first column of R, and so on. These are numerical values for the eigenpairs. To get symbolically ... version of the command, but it does give a cross-reference to the symbolic version at the bottom. If you want to see the help text for the symbolic version instead, type help sym/factor. Functions ... accepts vector arguments, then f(A) is the matrix obtainedby applying f element-by-element to A. See what happens when you typesqrt(A), where A is the matrix defined at the beginning of the Matricessection...
