`R=a(log2(1+b*c/a*d))`

in above equation “a” and “b” are variables.

i write this equation in cvx but could not run.

is this equation ok for above?

`-rel_entr((a*d),((a*d)+(b*c)))/log(2)`

If you tried putting in some “random” numbers for the variables, you would see that is not equivalent to your original formula.

`-rel_entr(a,a+b*c/d)/log(2)`

or `-1/d*rel_entr(a*d,a*d+b*c)/log(2)`

will work.
