MATLAB中做界面的时候
Error using ==> guihandles
H must be the handle to a figure or figure descendent.
请问是哪里错了
该怎么改啊
急用

贴代码出来，你这是报错信息，gui的句柄用错了

直接贴代码啊。。。

同等待matlab代码ing。。。

代码贴出来

不贴代码，还不如直接去找人翻译

以为我来错了呢 好高深啊……

function varargout = im2bw_args(varargin)
% IM2BW_ARGS M-file for im2bw_args.fig
%      IM2BW_ARGS, by itself, creates a new IM2BW_ARGS or raises the existing
%      singleton*.
%
%      H = IM2BW_ARGS returns the handle to a new IM2BW_ARGS or the handle to
%      the existing singleton*.
%
%      IM2BW_ARGS('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in IM2BW_ARGS.M with the given input arguments.
%
%      IM2BW_ARGS('Property','Value',...) creates a new IM2BW_ARGS or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before im2bw_args_OpeningFunction gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to im2bw_args_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
