Why does the ISEQUAL function return "1" (true) on FINTS objects when they are not actually equal?

The following code returns "true" even though the FINTS objects "fts" and "fts2" have different values:

dates = [today:today+9]';

reihe1 = [1:10]';

fts = fints(dates, reihe1);

fts2 = fts * 2;

isequal (fts, fts2)

 ans = 1

This bug has been fixed for Release 14 (R14). For previous releases, please read below for any possible workarounds:

This is a bug in the Financial Series Toolbox in the way that the ISEQUAL function compares FINTS objects.

As a workaround, you can edit the ISEQUAL function in order to have it compare the FINTS objects correctly. To edit the ISEQUAL function,

1) Type

edit fints/isequal

2) Save this as "isequal.m.old".

3) At line 41, remove the word "end". At line 51, add the word "end". The last part of the ISEQUAL function should then look as follows:

         elseif (arg1Time == 1) & (arg2Time == 1)

              if any((arg1.data{5} - arg2.data{5}) > (0.001/60/60/24))   

              % Check times. tolerance of .001 of a sec

                  iseq(oidx) = 0;

              end

          else   % Check data series names.

              eval('iseq(oidx) = ~any(any(char(sort(arg1.names(4:end)))-char(sort(arg2.names(4:end)))));', ...

                  'iseq(oidx) = 0;');

              if iseq   % Check values.

                  eval('iseq(oidx) = ~any(any(arg1.data{4}-arg2.data{4}));', ...

                      'iseq(oidx) = 0;');

              end

          end

      end

end

iseq = all(iseq);

% [EOF]

4) Save this as isequal.m
