<>Hi there,</P>
<>Who can help to show me the code for Simplex? thanks a lot!</P>
<>My equation is:</P>
<P>p(1)* y'' + p(2)*y + p(3)*y^3 = x</P>
<P>Now I know the data of x and y (they are vectors),the target is to find the parameter of p(i). </P>
<P>x and y are functions of t, meaning x(t) and y(t).</P>
