I want to use taylor function in CVX, but it looks like that CVX doesn't support the syms variable by taylor, can you help me plz?

1

syms x1 H x2
f = Hx2x1;
f2=vpa(taylor(f,[x1,H,x2],[0.45,30,0.45],‘order’,2));
cvx_begin
cvx_solver Mosek
variables x1 y1 y2 H x2
maximize H
subject to
0<x1<0.98
0<x2<0.98
0.9<x1+x2<1
y1< 8
y2< 8
-rel_entr(x1,x1+16y1)-rel_entr(x2,x2+3y2)-f2>0
cvx_end

syms variables are not supported by CVX.

Either convert the symbolic results manually, or come up with some automated way of doing the conversion. See How to convert Matlab symbolic variables to cvx variables
