octave: Diagonal Matrix Functions
21.3.1 Diagonal Matrix Functions
--------------------------------
“inv” and “pinv” can be applied to a diagonal matrix, yielding again a
diagonal matrix. “det” will use an efficient straightforward
calculation when given a diagonal matrix, as well as “cond”. The
following mapper functions can be applied to a diagonal matrix without
converting it to a full one: “abs”, “real”, “imag”, “conj”, “sqrt”. A
diagonal matrix can also be returned from the “balance” and “svd”
functions. The “sparse” function will convert a diagonal matrix
efficiently to a sparse matrix.
