1. matlab里那个fastica程序不会用啊
这个问题太专业了，你看看帮助文档吧，我手头也没有这个工具箱。
2. icalab的使用方法
因此，若是要准确纪录他们的历史，则必需使用另一种更为精炼的计日方法。 （而再更高位，但极少被使用的四个单位依序为Pictun、Calabtun、Kinchiltun
3. 求助。FastICA工具箱怎么汉化
函数原型 void reversestring(char s[],int n); 修改内容 #include void main(){ int i,n; char p[]="hansunguniversity"; n = strlen(p); printf("%c",p[i]); }
4. matlab怎么添加zmap工具箱

这个是NC-fastica，可以用。稍微注释了些
原始程序，不知道是谁写的了
6. fastica25工具箱都是一些.m的文件，应该如何在matlab中使用
这是成员初始化列表。A(n)就是调用A类的构造函数 A（n)来初始化基类A的数据。ob(n)就是给成员ob赋初值n。
7. 求Fastica在matlab中的源程序，包括数据的预处理（中心化和白化），很急，多谢了！
CSDN上都可以下载得到
