Minimizing the function

Hi, I would like to minimize the functions " A=2*x.^2-1.05*x.^4+1/6*x.^6-x.*y+y.^2 " , " f=-20*exp(-0.2*((x.^2)/2).^0.5)-exp((1+cos(2*pi*x))/2)+22 " by using two methods _Newton Raphson and Fletcher-Reeves conjugate gradient_method

HINT:“fmin” used in the implementation of Fletcher-Reeves in Numerical Methods using MATLAB is obsolete and replaced by “fminbnd”.

Please show me the way how I should do that. Thanks

If you want help with your homework, you should first show what you have attempted yourself, and ask specific questions about where you are stuck. We will not simply do your assignment for you.
