Details:

a=strread('1.0,'%g') is incorrect, but:

octave 3.6.4 reports an 'out-of-bound' error:

octave:1> a=strread('1.0','%g')
error: strread: A(I): index out of bounds; value 1 out of bound 0
error: called from:
error:   /usr/share/octave/3.6.4/m/io/strread.m at line 287, column 7
octave:1>

Would be nice to have a more informative message,
as in matlab R2012b:

>> a=strread('1.0','%g')
Error using dataread
Badly formed format string.

Error in strread (line 49)
    [varargout{1:nlhs}]=dataread('string',varargin{:}); %#ok<REMFF1>
