Description: This implementation of Isometric Method was designed with respect to be
used by a broad scientific community in different regions of science and
engieneering. As a consequence specific demands of particular branches may not
be fully satisfied.
Interested persons are encouraged to test this code at his/her own risk. We do not
guarantee absolutely perfect functionality when used in all possible configurations.
The Isometric method is subject of permanent development. Consequently the IM
code is from time to time revised and improved. Please follow this web page.
In case of using IM, please do not forget to make reference to the authors of
this algorithm (e.q. Malek et al.2007):

Description: 1、使用环境：
目前所编的工具箱的可视化界面可在MATLAB 7.0 版中使用，在7.4以上版本还有点问题，
至于7.0以下版本没有试用不知道可不可以。
2、文件存放路径：
inverse_toolbox 文件夹中的 inverse 文件夹应存放在 MATLAB 的 toolbox 文件夹中；
inverse_help 文件夹中的 inverse 文件夹应存放在 MATLAB 的 help 文件夹 中的 toolbox 文件夹中。
3、安装方法：
（1）先在 MATLAB 主界面窗口的菜单栏中选择 File->Set Path,
在添加路径窗口中添加以下三条路径：
...\toolbox\inverse
...\toolbox\inverse\inverse
...\toolbox\inverse\inversedemos
（save）保存即可
（2）点击主界面下方按钮 Start->Desktop Tools->View Sources Files...
打开 Start Button Configuration Files 窗口，点击 Refresh Start Button 刷新，
关闭该窗口即可在 MATLAB Help 浏览器中查看本工具箱的帮助信息
注：工具箱具体的使用方法请参见帮助。

1, using the environment:
Currently make up the toolkit of visual interface can be used in the MATLAB version 7.0, in 7.4 above and still have some problems,
As for the following version 7.0 no trials may don t know.
2, file storage path:
Inverse_toolbox folder inverse folder should be stored in the toolbox of MATLAB folder
Inverse_help folder inverse folder should be stored in the toolbox in the MATLAB help folder folder.
3, installation method:
(1) in MATLAB before the main interface window menu bar, select the File- > Set Path,
In the path of add window to add the following three:
... \ toolbox \ inverse
... , toolbox, inverse, inverse
... \ toolbox \ inverse \ inversedemos
(save) can be saved
(2) click below the main interface button to Start- > Desktop Tools- > View Sources Files...
Open the Start Button Configuration Files window, click Refresh Start Button Refresh,
The window can be closed this toolbox in the MATLAB Help browser to view the Help informat- 7.4 above and still have some problems,
