最近在做DCC-GARCH模型，之前从来没搞过GARCH模型，所以有很多的问题，下面是在利用MTALB中的Ucsd_garch工具箱中DCC-GARCH模型程序，运行出现下面的错误。
Estimating GARCH model for Series 3
Warning: Options LargeScale = 'off' and Algorithm = 'trust-region-reflective' conflict.
Ignoring Algorithm and running active-set algorithm. To run trust-region-reflective, set
LargeScale = 'on'. To run active-set without this warning, use Algorithm = 'active-set'.

Error using optimset (line 199)
The LevenbergMarquardt option is no longer valid. Set the Algorithm option instead.
