how to know the current m-file directory in the mfile

[olinn]

I want to open a file with the path like this [current m-file dir]\file\filename.txt. I found i cannot do like just textread('file\filename.txt'..) in the m-file. so i think i should know the m-file directory itselt first, then do the job. do anyone know how to do this? thank you!

no, when pwd used in m-file, it still returns the current work directory of matlab, not the m-file directory itself.

i got an ugly way,

s = mfilename;
s = which(s);
then delete the mfile name in the string s.....

 

[brokensoul]

Use / instead of \

try something like

cd('c:/path')
textread('filename')

This what you needed?

no. I need to know the current running m-file path dynamically to keep the m-file function has better adaptability when moving the m-file.

Another approach, which appears to be more gruesome, is to use depdir on the current file. Unfortunately, it takes a while, since it crunches through the entire path and the last entry is the current directory of the m-file.
