Thank you. So the new implementation choice about how to handle bad
inputs also seems to break the compatibility with MatLab (which
existed before) and old octave versions.
I don't know C so the only workaround I have at the moment is to make
a new function that calls the C optimized version of str2double adn in
case of errors replaces all non-strings by strings:
function out = str2double(in)
try
out = str2double_optimized (in)
catch
for i:1:numel(in)
if (!ischar (a{i})) a{i} = "nan"; endif
endfor
out = str2double_optimized (in)
end_try_catch
I'm sure someone smarter will think of something better than this.
