当我在提示符下输入wavemenu时,出现以下信息:??? Error: File: openfig.m Line: 68 Column: 17The construct "min(...end...)" is ambiguous in this context, because "min" cannot be ascertained to be either the name of a variable or of a function. To make it a variable, assign to it; to allow it to become a function at execution time, replace "end" with a call to LENGTH, SIZE, or NUMEL on the desired array.Error in ==> gui_mainfcn>local_openfig at 223 gui_hFigure = openfig(name, singleton);Error in ==> gui_mainfcn at 94 gui_hFigure = local_openfig(gui_State.gui_Name, gui_SingletonOpt); Error in ==> wavemenu at 61 gui_mainfcn(gui_State, varargin{:});请问这是什么原因?是这个工具箱需要重新安装还是盗版软件的原因?
