I defined a variable FQB as 0:0.01:1 but when I use this I get a FQE as a single constant despite using FQB to define it.
x is an array but logitx is somehow a constant as well. What am I doing wrong? I am trying to plot FQB vs FQE
D0 = 100;
D1 = 80;
D2 = 80;
HD = 0.4;
A = -6.96*log(D1/D2)/D0; % A is 0 for symmetric bifurcations
B = 1 + 6.98*(1-HD)/D0;
X0 = 0.4/D0;
FQB = 0:0.01:1;
x = (FQB-X0)/(1-2*X0);
logitx = log(x/(1-x));
FQE = 1/(1+exp(-(A+B*logitx)))
FQE = 0.3206
