Matlab'；NC#u UNLIMITED在错误的索引中'；在NetCDF文件中写入无限时间维度时

我正在尝试编写一个具有无限时间维度的NetCDF文件，并且正在努力获得成功。我非常感谢您的帮助：）

此处显示错误消息：

使用netcdflib时出错 NetCDF库在执行“defVar”函数期间遇到错误- “错误索引中的NC_UNLIMITED（NC_eunlemon）”

netcdf.defVar中的错误（第38行）

varid=netcdflib（'defVar'，ncid，varname，xtype，dimids）

为HRLDAS\u 05\u 06\u 2013\u unix\u wong\u 100x120创建\u nc\u时出错（第193行）

varid_Q2D=netcdf.defVar（ncid，'Q2D'，'float'，[Time west\u east south\u north]）

“错误索引中的NC_UNLIMITED（NC_eunlimpo）”是什么意思？

无限制维度

时间

需要是Matlab中的最后一个维度（Matlab与大多数其他NetCDF实现相反）。因此，只需定义变量，如：

varid_Q2D = netcdf.defVar(ncid,'Q2D','float',[west_east south_north Time]);

你应该没事的
