function varargout = demand(varargin)
% DEMAND MATLAB code for demand.fig
% DEMAND, by itself, creates a new DEMAND or raises the existing
% singleton*.
%
% H = DEMAND returns the handle to a new DEMAND or the handle to
% the existing singleton*.
%
% DEMAND('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in DEMAND.M with the given input arguments.
%
% DEMAND('Property','Value',...) creates a new DEMAND or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before demand_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to demand_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".

when i run this gui program, i get this error massage
what should i do
sum =
0
Array indices must be positive integers or logical values.
Error in demand>demand_push_Callback (line 332)

for t=2:200
sum=0
for j=2:t
sum=sum+sum(t-j).*f(j)
end
v(t)=sum
end
t starts at 2. j starts at 2. t-j starts at 0. sum starts at the scalar 0. sum(t-j) would be sum(0) which is an invalid index.
The associated logic never stores more than 1 value in sum so sum can only be indexed at 1 (or true)
Reminder that matlab does not support implied multiplication. If you want multiplication then you need to use a multiplication operator.

Here ! means the open-bracket count has gone to negative 1.
