hello i have matlab 7.9 R2009b and i cannot run my m files that i create i have not completely understood in which file they must be located so that i can run them i have tried the MATLAB file that the programm created in my documents file i have also tried the matlab/bin file (i have ubuntu and matlab is installed in my home directory, unfortunately) but none of these worked :( when i try to run the m file, a window appears that is saying "file is not found in the current directory or in the matlab path. to run this file u can either change the matlab current directory or or add its directory to the matlab path" and then then u can choose either "change directory" or "add to path" but none of these work, too please, i would really appreciate it if anyone could helo

Are you sure. Always, that I've seen, if you have open an m-file in the editor and click the green Triangle to run it, and it says you can change directory and you do so, it will then run the file. Are you saying you just click and the button goes away and absolutely nothing at all happens?

Use a string instead of numbers for naming *.m file (e.g. abc.m instead of 1.m). then try it

Correct. MATLAB .m file names must follow the rules for naming variables. The first character must be a (Latin) letter, and following characters can be (Latin) letters or (Latin) digits or the underscore ('_')

Make sure the filenames end in .m and there is no hidden extension. Make sure the files are readable by you. Put the files in a convenient directory that does not have MATLAB installed in it. Start up MATLAB. Use pathtool to add that directory to the MATLAB path. You should now be able to invoke the code by giving the base file name without the directory and without the extension.
If it is not able to find it, then try using "which" to see what it says. For example if the file is MyProgram.m then
which -all MyProgram
