function T = CreateDatabase(TrainDatabasePath)
% Align a set of face images (the training set T1, T2, ... , TM )

% Description: This function reshapes all 2D images of the training database
% into 1D column vectors. Then, it puts these 1D column vectors in a row to
% construct 2D matrix 'T'.
% Argument: TrainDatabasePath - Path of the training database
% Returns: T - A 2D matrix, containing all 1D image vectors.
% Suppose all P images in the training database
% have the same size of MxN. So the length of 1D
% column vectors is MN and 'T' will be a MNxP 2D

Error in CreateDatabase (line 2)
functions T = CreateDatabase(TrainDatabasePath)
>> CreateDatabase
Error using CreateDatabase (line 23)
Not enough input arguments.
Please help me in this code..Thanks in advance

CreateDatabase('C:\Prgram Files\MATLAB\R2009b\work\face recognition');
use in this format instead of that

How to give the path of image as an argument to createdatabase function?

Well, eveidently it wants another input argument. Why don't you just simply supply all the input arguments that it requires? You can't do this:

Not enough input arguments.
Look at the definition. CreateDatabase() requires a string that is a folder as an input. You did not supply that -- you just called it without supplying ANY arguments. Why didn't you supply the folder that it wants???
