Its a floating point error down at the 5th significant figure. If you simply round "Px", it'll MAY work

Px(var_ab _ var_ae) is not valid syntax. Possibly you meant
Px(var_ab - var_ae)
If so then you would be attempting to subtract the two variables and use the result to index the array "Px".
Possibly you intended multiplication,
Rx = log2((1 + Px*(var_ab - var_ae)+(1 +var_ae*Pw +Pb*var_be.^2+ 2*sqrt(Pb*Px*var_ab*var_ae))));
