How to define a logrthimic expression in cvx

1

I have a expression, \text{log}{2}\left( 1+(P{1}\left|\bm{v_{1}}^{\rm{H}}\bm{\xi} {12}+\text{h}{w_{12}}\right|^2)/N_{0}\right)

where P_{1} is a variable, rest all parameters are defined.

You can enter log2(x) as log(x)/log(2)

Other than that, you should be able to enter it “as is”.

thanks for that help. I thought there is keyword for writing the log. I read about rel_enter so got confused.
