matlab 读取EXCEL文件关于版本问题
本人在学习视频过程当中！！自己按照老师的做法模仿程序
当用xlsread函数读取时候却出现问题！！本人看了一下问题提示，大体上我感觉应该是版本问题！！但是我的版本是2003，难道读取文件函数有改动吗？此问题应该如何处理！！！？ 敬礼
代码如下： str=[PathName FileName];
set(handles.edit1,'string',str)
%fin=fopen(str,'r');
[chengji xingming]=xlsread(str);
提示问题如下FileName =
chengji.xls

PathName =
D:\MATLAB6p5\work\

test =
.xls
