hi Teeam,

I have new to the matlab and we have requirement here. I am running query using oracle database. For each row data(5 columns), I will call another function which will run another query internally using those row data. But output for each single row will be a column of multiple rows. I am using rowfun and an getting below error. Please help me out.

p_returns = rowfun(@Func,T(1,:)); -- sending only row for time being

but i am getting below error :

Error using table/rowfun (line 256) The function 'Func' returned an output with more than one row when applied to the 1st row in A.

Error in sharpe_ratio2 (line 63) p_returns = rowfun(@Func,T(1,:));

Can rownfun does not take multirow output for single row input.
