MATLAB资源连接器配置为：$C:\Users\Administrator\Desktop\AccessTest/sqljdbc42.jar。
matlab执行代码为：databasename='test'; %数据源名称
username='lxx'; %登录名
password='lxx'; %密码
driver='com.microsoft.sqlserver.jdbc.SQLServerDriver';
% databaseurl=['jdbc:sqlserver://localhost:1433;database=',databasename];
databaseurl=['jdbc:sqlserver://localhost:1433;databaseName=',databasename];
conn = database(databasename,username,password,driver,databaseurl);
ping(conn)
