matlab调用数据库问题
以下是我用matlab调用sql2000画图的程序，可以顺利画图。但是现在要用matlab调用sql2005,一调用好像识别不了行列似的，错误直接就是：
??? Attempted to access dis(:,3); index out of bounds because numel(dis)=1.
Error in ==> petridata at 28
dis_order=dis(:,3)';
请高手帮忙指导！
clear all
close all

timeout=logintimeout(5);
% Connect to a database.
conn=database('PetriSCM','sa','123');
setdbprefs('DataReturnFormat','numeric');
% Check the database status.
totaltime=2000;
cursor_dis=exec(conn,'select step,inventory,orders,inventory1,inventory2,Cost from distributor');%执行SQL语句和打开油标
cursor_dis=fetch(cursor_dis,totaltime);%导入数据到MATLAB单元数组
dis=cursor_dis.Data;
dis_order=dis(:,3)';
dis_inventory=dis(:,2)';
dis_Cost=dis(:,6)';
