Tridiagonal Decompositions Click on the banner to return to the user guide home page.
Since decompose uses the abstract base tridiagonal decomposition class, its code works equally well for dense or band decompositions. When you ask a server for the decomposition of a matrix, the default base server computes the appropriate symmetric tridiagonal decomposition, uses decompose to do the computation for the tridiagonal matrix, and then transforms the results so they apply to the original matrix.
