%Import data

if nargin==0
    filen=load(filename,'mp1')
      [filen,path]=uigetfile('*.mat;*.gif',...
          'Pick your file');
  else
      [path,filen,ext]=fileparts(files);
      path=[path '\'];
      fs=filesep;
      if ~isempty(path), path=[path fs]; end
      filen={[filen ext]};
  end

how to load file automatic?

mean: to load file (just call extension not file name) in specific directory.

I have 5 MAT-files and 1 RAR-files in the directory 'Database'. Then I want to load MAT-files only from the directory. This is the code :

clear all; clc;
files = dir(strcat(pwd,'\Database\'));
for x = 1 : size(files,1)
    [path{x}, name{x}, ext{x}] = fileparts(files(x).name);       
end
for x = 1 : size(files,1)
    if  strcmp(ext{x},'.mat')
        load(strcat(pwd,'\Database\',name{x},'.mat'));         
    end
end

---------------------------------------------------------

This code is used to load MAT-files only from the selected directory. You can change the directory by changing

files = dir(strcat(pwd,'\Directory\'));

And you also can change the file extention by changing

if strcmp(ext{x},'Any file extention')

and

load(strcat(pwd,'\Directory\',name{x},'Any file extention'));

Good. For my case I want the user to enter the extension in the command window and it loads all those files automatically. It should load in the current directory I am working. No need of changing directory.
