.mat问题图片处理?谢谢
我的图片名wavelet.bmp
我输入
I=imread('wavelet.bmp')
save wavelet
于是在WORK文件夹里面出现了wavelet.mat文件(我这么保存有错误么?)
下面是我程序的一段 运行有错误
load wavelet;
whos%
[swa,swh,swv,swd] = swt2(X,1,'db1');
whos
figure(1);
错误提示
?? Undefined function or variable 'X'.
Error in ==> F:\学习\Matlab\work\jiequzao.m
On line 3 ==> [swa,swh,swv,swd] = swt2(X,1,'db1');
谁能帮帮我啊?
