HI,
I would like to know the possibility of creating a temporary file in a specified drive rather than in c:\....temp\. using the matlab function name "tempname". My OS in windows 7 and the program is not running in C drive. So when I import the created file using the function "importdata". It shows an error
??? Error using ==> importdata at 136
Unable to open file.

请先登录，再回答此问题。

The function ...
getenv('TEMP');
shows the current path of the temporary directory in which the temporary files will be generated on your system. The TEMP environment variable will hold this path.
For changing this path to your desired directory use... say 'C:\'
setenv('TEMP','C:\');

You can import a file from wherever directory it is. Just point to the full direction:
importdata('D:\my_dir1\mydir2\my_Data.mat');
To create a new temp file, you can follow this instruction:

Once you change the location of your temp file,
tmp_folder = tempdir;
will return the new location.
