[求助]MATLAB画图问题，caxis.m的问题

近日在用evolutionary spectrum做一个序列的周期分析，碰到如下的问题：
??? Error using ==> set
Bad value for axes property: 'CLim'
Values must be increasing and non-NaN.

Error in ==> caxis at 80
set(ax,'CLim',arg);

Error in ==> EVspctrm at 125
caxis(10*log10([SCv(idCv) mxE]))

因此上网找答案，找到了一个相近的问题：

??? Error using ==> set
Bad value for axes property: 'XLim'
Values must be increasing and non-NaN.

Error in ==> D:\Applications\MATLAB6p5\toolbox\wavelet\wavelet\wptreeop.m
On line 573 ==> set(WP_Axe_Pack, ...

??? Error while evaluating text ButtonDownFcn.

给出了如下的解释：
This is a bug in the way the Wavelet Toolbox 2.2 (R13.0.1) displays the decomposition tree for certain signals.

You can download a revised version of an M-file that fixes the problem.

因此，我想是不是我的caxis.m文件出了问题？是不是找一个更新就可以？但可惜的是，找了两天也没能找到caxis.m文件，虽说也找到了和我遇到相同问题的，但没有给出问题的解答，恳请各位大侠不吝赐教，thanks in advance.
