Hi everybody,
I wrote a function that get 4 parameters (one of them char = file name, and the other is arraies) and should open a file that his name was given, and some manipulations. function call looks like this
Amplitude_lie_det(file_name,qu_num,time_arr,answer_arr)
and I got an error :
??? Undefined function or method 'Amplitude_lie_det' for input arguments of type 'char'.
I will be very glad if someone that "meet" this error before can give me an advise...
thanks, Ashraf

You may check the type of your first parameter in the function,the error means you call your function with a mismatch parameter type(the first one)!

Check that the function is on the MATLAB path with:
which -all Amplitude_lie_det
If it says 'Amplitude_lie_det' not found, then add the path where the function is located to the MATLAB path:
addpath 'c:\yourpath'
or File > Set path > Add folder.

And make sure the routine is stored in a file named Amplitude_lie_det.m

Your initial issue is solved: if you think that my or Guo's suggestion helped you solve it, then accept one of the answers.
Then,since you're asking another question I suggest to post a new thread. You will get more attention from a wider pool of contributors and the chances to get an answer will not be tied to those that participated to this thread only.
