Oracle to_date function in Matlab

Hello-- in TOAD when I write the following SQL code to insert a record into an Oracle database:

insert into ALG_IMP_SCHEDULE(TIME_PERIOD_KEY, SCHEDULE_DATE) values ('100',to_date('4/1/2012', 'm/d/yyyy'))

it works fine, but when I try to replicate this in Matlab with the code:

colnames = {'TIME_PERIOD_KEY','SCHEDULE_DATE'};
exdata = {'100','to_date(''4/1/2012'',''MM/DD/YYYY'')'};
insert(connALG, 'ALG_IMP_SCHEDULE', colnames, exdata);
cursor = exec(connALG, 'commit');

I get a Matlab error citing an Oracle error:
Error using ==> database.insert at 178
ORA-00917: missing comma

any idea why??

Thanks.

I've never heard of matlab...so I had to go looking (I was curious).

From the few minutes with Google and Matlabs homepage....it appears it 'should' work.

Just for grins to help troubleshoot try the following change:
exdata = {'100','sysdate'};


My guess is Matlab is interpreting the information as a 'string' and not a 'value' to pass off to Oracle to interpret.

Nevermind, I figured it out... if there's a way to do this with the Matlab insert function that incorporates the Oracle to_date function then I still don't know what it is, but I just worked around it by writing a query string and executing it:

sqls = ['insert into ALG_IMP_SCHEDULE(TIME_PERIOD_KEY, SCHEDULE_DATE) values (''', datestr('09/09/2010','yyyymmdd'), ''',  to_date(''','10/3/2011'',''mm/dd/yyyy''))'];
cursor = exec(connALG, sqls);
cursor2 = exec(connALG, 'commit');
