[求助]关于工具箱安装的问题

[polyanna]

我装了高阶谱工具箱，为什么运行后出现如下问题？
输入命令：HOSAVER
出现warning如下：
Warning: Could not find an exact (case-sensitive) match for 'HOSAVER'.
D:\Program Files\MATLAB\R2006a\toolbox\matlab\hosa\HOSAVER.M is a case-insensitive match and will be used instead.
You can improve the performance of your code by using exact
name matches and we therefore recommend that you update your
usage accordingly. Alternatively, you can disable this warning using
warning('off','MATLAB:dispatcher:InexactMatch').

请各位高手指点
