% the program is with the unconstrained nonlinear programming
% please input the parameter matrices and the standard form of the matlab optimization

% The programming is to solve a particular example of unconstrained nonlinear programmming!

 % min e^(-x)+x^2

function f=unpfun1(x)

% if you debug , you can use the three input

% input('The program is with the unconstrained nonlinear programming')

%x=input('please input the initial number of the pivot element x=')

%input('Please Use the standard form in the toolbox:')
