+function fig_export(filename, format, folder, dpi, fig)
+    % EXPORT_CHART Save the current MATLAB figure or a specified figure in the selected image format.
+    %
+    % Parameters:
+    % - filename (string, optional): The output file name. If it has no extension, one will be
+    %                                added based on the format. If missing or empty, a default
+    %                                name 'exported_plot' is used.
+    % - format (string): The desired file format for the export. Default is 'pdf'.
+    %                    Accepted formats are 'png', 'jpg', 'tiff', 'svg', 'pdf', 'esp'.
+    % - folder (string): The directory where the image file will be saved. Default is the current directory.
+    % - dpi (int): Resolution in dots per inch. Default is 96.
+    % - fig (figure handle, optional): The MATLAB Figure object to export. If empty, the current active figure is used.
+    %
+    % Notes:
+    % - The function creates the folder if it doesn't exist.
+    % - Ensures compatibility with supported MATLAB formats.
