Change ~isempty by isfield

[Jasosahe01]

Hi!

I suggest you to change line 63 on STBLFIT.m
if ~isempty(opt.MaxIter)
by
if isfield(opt,'MaxIter')

and line 66
if ~isempty(opt.TolX)
by
if isfield(opt,'TolX')

Regards!

Thanks for the feedback!

These should always be fields if opt is created with statset. However if you want to pass in your own struct then we would still need to handle the case where MaxIter or TolX are empty. How about this instead?

if isfield(opt,'MaxIter') && ~isempty(opt.MaxIter)
if isfield(opt,'TolX') && ~isempty(opt.TolX)
