Sir/Madam, I need help to execute for loop. Please help me. this program can't check about the user is exists or not.. Please help me where I'm wrong.
function varargout = home(varargin)
% HOME MATLAB code for home.fig
% HOME, by itself, creates a new HOME or raises the existing
% singleton*.
%
% H = HOME returns the handle to a new HOME or the handle to
% the existing singleton*.
%
% HOME('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in HOME.M with the given input arguments.
%
% HOME('Property','Value',...) creates a new HOME or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before home_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to home_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
%
% See also: GUIDE, GUIDATA, GUIHANDLES
% Edit the above text to modify the response to help home

The only for loop in the code is:
for i = numel(curs.Data)
It runs for 1 iteration only. Perhaps you want:
for i = 1:numel(curs.Data)
