How to solve this problem {convex} ./ {real affine}

[Young (Yang Jiankun)]

Hi,
I want to write

 R1(k,1)=(rel_entr(t(k,1)+t(K,1)^2*delta^2/(p_p(k,1)*g(k)^2),t(K,1)^2*delta^2/(p_p(k,1)*g(k)^2))+rel_entr(t(K,1)^2*delta^2/(p_p(k,1)*g(k)^2),t(k,1)+t(K,1)^2*delta^2/(p_p(k,1)*g(k)^2)))/log(2);

for the first expressions R1(K,1);

But
Disciplined convex programming error:
Cannot perform the operation: {convex} ./ {real affine}

Please help me!

How to express the function in CVX?

I want to express this function in CVX: [fomula] According to the perspective function, the concavity of part ② equals to the concavity of -log2(1+p), which is convex. So the function is convex. My code is as follow variables mu_t,beta,p are nonnegative; B,D,No,h are constant; miut - Bbeitalog2(1+phinv_pos(NoBbeita)) <= 0; When I running it , I got this error Disciplined convex programming error: Cannot perform the operation: {real affine} .* {convex}

and, please use a markdown format to write the code if convenient.

I see, thank you so much!
