Dear all,
I wrote some Matlab programs (several M files and functions) and saved them in a folder. I successfully ran these programs after finised writting. However, after I surfed Internet for a while and got back to ran them again, there were strang errors. For example, when I ran a file called Test.m I wrote, it complains
??? Undefined function or variable 'Test'
And it happens to all other programs (within the same folder) as well. If I copy them to a different drive or different folder, the error still occurs to some of the programs.
Would you please tell me why this happened and how to solve it?
Many thanks and I look forward to your reply.
Sincerely, Jinlong.

Make sure the folder they are in is in the MATLAB search path.
File > Set Path ...

Try changing the current MATLAB directory to the folder containing your M-files, or else adding that folder to your MATLAB path, using the addpath function or the path tool.

Dear Jon and David,
Thanks for your suggestions. However, seems the problem is more strang, as I used the addpath function and the path commend shows the directory has already been added in but the same problem still there!
Also, I have another parallel folder where the programs I wrote can run without any problem! You may suggest me to put the programs in that parallel folder. Yes I did it but the problem is the same. My computer adminstrator has installed a new version Matlab for me, however, the problem is not solved.
Really get surprised on what happened.
Thanks.
Jinlong.
