如何将变量附加到.mat文件? [英] How to append a variable to a .mat file?

问题描述

如果我已经有一个包含变量x和y的.mat文件，有没有一种方法可以使用save命令向.mat文件中添加另一个变量z，而不必在save命令中明确声明变量x和y?

If I already have a .mat file with the variables x and y, is there a way to use the save command to add another variable z to the .mat file without having to explicitly state the variables x and y in the save command?

推荐答案

如果您查看

If you look at the save() function documentation, there is a form of the save command that might help:

save(filename, ..., '-append')

此表单的帮助如下:

save(filename, ..., '-append')将新变量添加到现有文件.您可以将"-append"选项与变量，-struct"，格式或版本等其他输入一起指定.

save(filename, ..., '-append') adds new variables to an existing file. You can specify the '-append' option with additional inputs such as variables, '-struct' , format, or version.
