然而,对于简单的矩阵数据写入CSV文件的任务,csvwrite仍然是一个有效且简便的选择。如果你使用的是MATLAB的较新版本,并希望使用更新的函数,可以考虑使用writematrix函数,如下所示: matlab writematrix(data, filename); 这将执行与csvwrite相同的功能,但使用的是MATLAB推荐的现代方法。
除了上述使用csvwrite(函数之外,还可以使用writematrix(函数将矩阵写入CSV文件。这是MATLAB R2024a中新增的函数。使用方法如下: writematrix(A, filename, 'Delimiter', d) writematrix(A, filename, Name, Value) -A是要写入文件的矩阵。 - filename是要保存的CSV文件的名称(包括路径和扩展名)。 - 'Delimiter'...

col is zero-based, so that col = 0 instructs MATLAB to begin writing in the first column of the destination file. Skipped columns are separated by commas. Limitations csvwrite writes a maximum of five significant digits. If you need greater precision, use dlmwrite with a precision argument....
