八度音程包自行卸载

Question

I'm using the Octave io package but it keeps unloading itself before I run the script. I'm using the xlsread function provided by io but I keep getting the following error:

warning: Functions for spreadsheet style I/O (.xls .xlsx .sxc .ods .dbf .wk1 etc.) are 
provided in the io package. See <http://octave.sf.net/io/>. 
Please read <http://www.octave.org/missing.html> to learn how you can contribute missing 
functionality. 
error: 'xlsread' undefined near line 25 column 23

The package shows up when I type pkg list and there is an asterisk next to it when I type pkg load io . I even edited the octaverc to load io on startup. But I get that error when I run my script and when I check pkg list after my script fails the package is unloaded.

确保不要在脚本中的某处调用clear all （或类似的命令），因为这也可能会从内存中删除已加载的库。
