GroupOrder flag does not seem to work as expected

[ManuelaS]

Hi,

I tried to reorder the groups from the LAML example to have “N.D.” at one extreme ('Poor', 'Intermediate', 'Good', 'N.D.') using the flag “GroupOrder” and I got the error below.
`
load('laml_RC_data.mat');

[p, fh, stats] = MatSurv(...
laml_RC_TimeVar,...
laml_RC_EventVar,...
laml_RC_GroupVar,...
'GroupOrder', {'Poor', 'Intermediate', 'Good', 'N.D.'})

`

Errors as

Conversion to logical from cell is not possible.
Error in MatSurv (line 293)
if options.GroupOrder

It looks like the flag is expected to get a boolean rather than a cell array with the group order as in the doc string.

Thanks for finding this! There was some changes pushed that may have broken this and I should have done a more detailed testing. Fixes to come soon

Fixed. It can now handle both a cell array and a scalar vector as input for GroupOrder.
