Undefined function 'loadfile' for input arguments of type 'char'.

I am suppose to run this function called Batch. Based on my understanding, I am suppose to import a file in .txt format. I have prepared/preprocess the necessary .txt file and configured the t_train_path to point to the directory where the file is located. But still I get this error.

below is the line of code from batch.m that is giving me the error.

% ----------------------------------------------------------------

% Load train file

% ----------------------------------------------------------------------

   % specify your training file here %
   % e.g. t_file = '\Dataset\My_folder\My_train_file.txt'
   % or use sprintf as below 
   % t_file = sprintf('\\DataSet\\D%d_%s_40_%dc(s).txt',1,'05',1);
t_file = '/Users/yongbenjamin/Desktop/Spiral/SpiralTrain_T.txt'
t_train_path = [pwd t_file];
train_set = loadfile(t_train_path);

% ---------------------------------------------------------------

------- //Code

>> cd /Users/yongbenjamin/Desktop/Spiral/

>> ls

SpiralTest.txt SpiralTrain.mat Spiral_T.txt

SpiralTrain.csv SpiralTrain_T.txt matlab.mat

>> Batch

t_file =

/Users/yongbenjamin/Desktop/Spiral/SpiralTrain_T.txt

Undefined function 'loadfile' for input arguments of type 'char'. Error in Batch (line 14) train_set = loadfile(t_train_path); //End of Code

loadfile() is not a Mathworks-supplied routine.

Where you thinking of load() ?

Hi walter,

Do you meant where did I get this loadfile() function from? This whole program is designed from internal use. And I am trying to figure out how to use it. Apparently the documentation on the various function was not done detailed. I just to load a .txt file into the system. I just tried, and apparent now it solve the problem from that line of code.

[Walter Roberson]

All we can do is make the generalization that loadfile.m must be on your MATLAB path; you can use pathtool to adjust your path. loadfile() is not supplied with MATLAB, so either it is supplied with your internal code or else the internal code is incorrect.

Walter,

i just checked through internal code file directory. It contain loadfile.dll instead of the loadfile.m. May I confirm with you if there is a possibility that the loadfile function is located within loadfile.dll instead. Apparent the train_set data doesnt seem right as well to me.. I am having problem with the other line of codes, probably due to this fault

[Walter Roberson]

Yes, there is the possibility of a problem if loadfile.dll is not recognized by your version of MATLAB, which could happen if you are using a 64 bit version of MATLAB and the .dll is 32 bit.

[Benjamin]

Hi walter, you are right. Any solution to work around this?

[Walter Roberson]

You can run the 32 bit version of MATLAB on a 64 bit Windows operating system, or you can rebuild the dll for 64 bit use.
