[Octave-patch-tracker] [patch #8837] normest1

[Marco Caliari]

Follow-up Comment #16, patch #8837 (project octave):

condest could be modified in order to use normest1. The syntax should be
changed, using AFUN like in normest1 instead of APPLY and APPLY_T. This does
not break the compatibility with Matlab (whose condest cannot be applied to
functions), but with the previous versions of Octave. In order to summirize,
we currently have:

1) onenormest, normest1 working both with matrices (same syntax) and with
functions (different syntax), normest1 compatible with Matlab

2) condest (estimates the condition number in norm 1) working both with
matrices (compatible with Matlab) and with functions (not supported in
Matlab), with syntax compatible with onenormest.

3) normest (estimates the norm 2) working with matrices (compatible with
Matlab), easy to extend to functions (not supported in Matlab) with the same
syntax of normest1.

A final situation (for me) could be:

1) condest1=condest, for matrices and functions, using normest1.
2) normest2=normest, for matrices and functions

The first step should be making deprecated onenormest and the current syntax
of condest. Sounds reasonable?
