用matlab对时域分析方法的设计界面，要求有电路 图或者传递函数（数学模型图）、参数修改框、波形显示框 等。

可以使用MATLAB的GUI设计工具来实现这个设计界面。以下是一个简单的示例：

1. 创建一个新的GUI界面，命名为"时域分析方法设计界面"。
2. 在界面上添加一个静态文本框，用于显示电路图或者传递函数。
3. 添加一个参数修改框，用于输入电路参数或者修改传递函数的系数。
4. 添加一个按钮，用于触发分析操作。
5. 在界面上添加一个波形显示框，用于显示分析结果。
6. 在回调函数中，编写时域分析方法的MATLAB代码，根据输入参数计算分析结果，并将结果显示在波形显示框中。

下面是一个示例代码，其中包含了一个简单的RC电路的传递函数及分析方法：

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