function varargout = Final_gui(varargin)
% FINAL_GUI M-file for Final_gui.fig
% FINAL_GUI, by itself, creates a new FINAL_GUI or raises the existing
% singleton*.
%
% H = FINAL_GUI returns the handle to a new FINAL_GUI or the handle to
% the existing singleton*.
%
% FINAL_GUI('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in FINAL_GUI.M with the given input arguments.
%
% FINAL_GUI('Property','Value',...) creates a new FINAL_GUI or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before Final_gui_OpeningFcn gets called. An

@Jan Sir the command we are using in our code is varargout
@Jan Sir we are currently doing a project on fingerprint tampering detection.We have built up a code for the same using MATLAB . We are thinking of intergarting this code onto DSP TMS320C series which takes in C/C++ Code .During the conversion of this code into C using MATLAB2018b coder we are getting errors as attached below
Sir is there any other method by which we can integrate this MATLAB Code directly onto DSP TMS320 series for the hardware implementation of this project.
note: the code provided is of the main file which calls the other files

Unfortunately you can't convert a GUI to C with coder. There are just too many elements that aren't supported.
You can package the code to an executable, which will require the use of the Matlab Runtime Compiler on the client computer.

It might be possible to convert the internal functions to C (depending on what functions are used exactly), but there is not a generally available way to convert a GUI (especially not one created with GUIDE) to C/C++.
I don't know anything about the specific hardware you mention. You should look up documentation for that device.
