(1 point)Theory: A matrix A is said to be orthogonally diagonalizable if there exists an orthogonalmatrix P ( 1 T P P = ) and a diagonal matrix D, such that, 1 A PDP = , or equivalently,T A PDP = .Theorem: An n n matrix A is orthogonally diagonalizable if and only if A is...
If a variable already exists in a MAT-file, then save overwrites it with the value in the workspace. For ASCII files, "-append" adds data to the end of the file. To append to a Version 6 MAT-file, you must also specify version as "-v6"....
