Hello Friends!

I hope you are well…

I want to write CVX code that solves the following expression(Entropy Rate):

max (x/x+y).*(H(y,1-y))+(y/x+y).*(H(x,1-x)) H(.):entropy

and gives me the optimal x,y to achieve the maximum of this function.

i know that this expression has a maximum value of 1 bit. and it occurs in x=y=1/2.

first i tried to write in DCP ruleset but i got an error:

```
cvx_begin
variable x
variable y
maximize (y/(x+y))*(entr(x)+entr(1-x))+(x/(x+y))*
(entr(y)+entr(1-y))
cvx_end
```

By reading more i got to know GP, but that didn’t work either!

can anyone help me pls…

thank u so much…
