[求助]??? Attempt to execute SCRIPT wavedec as a function.是什么错误．
>> load sumsin;s=sumsin;
subplot(2,1,1);
plot(s);
[c,l]=wavedec(s,5,'sym4');
a5=wrcoef('a',c,l,'sym4',5);
subplot(2,1,2);plot(a5)运行就出现以下错误：
??? Attempt to execute SCRIPT wavedec as a function.
我在toolbox中找到了所谓的wavedec.m文件
请教wave函数库是不是有问题
谢谢！！！
