[Octave-bug-tracker] [bug #64113] optimget should accept [] as first argument

[Muhali]

Follow-up Comment #4, bug #64113 (project octave):

Funny. I looked directly at my ML R2019b help, which one would think is the
same as

https://www.mathworks.com/help/releases/R2019b/matlab/ref/optimget.html?s_tid=doc_ta

But it is not. Here is what I get:

>> help optimget
 optimget Get OPTIM OPTIONS parameters.
    VAL = optimget(OPTIONS,'NAME') extracts the value of the named parameter
    from optimization options structure OPTIONS, returning an empty matrix if
    the parameter value is not specified in OPTIONS.  It is sufficient to
    type only the leading characters that uniquely identify the
    parameter.  Case is ignored for parameter names.  [] is a valid OPTIONS
    argument.
 
    VAL = optimget(OPTIONS,'NAME',DEFAULT) extracts the named parameter as
    above, but returns DEFAULT if the named parameter is not specified (is
[])
    in OPTIONS.  For example
 
      val = optimget(opts,'TolX',1e-4);
 
    returns val = 1e-4 if the TolX parameter is not specified in opts.
 
    See also optimset.
