Hi all,

I have a script that i can get probability dist. for qult.now i would like to have the distribution of qult and a deterministic number( like: 6.28)showing like bar(verticle line) with different color in output when for example using this command hist(qult).would anyone please help me.

my code :

clear
clc;
B=300; L=600;Df=200; Sgama=0.8; dgama=1;
nsamples=800;
rmem = zeros(3,nsamples);
for K=1:nsamples
  while true
           C = normrnd(.683,.062);
                if C<=.57 || C >= .8 || ismember(C,rmem(1,1:K-1)); continue; end
                     gama = normrnd(.00196,0.00002);
                           if gama <= .00192 || gama >= .00198 || ismember(gama,rmem(2,1:K-1)); continue; end
                                   fi = normrnd(3.6,.4885);
                           if fi <= 2.7 || fi >= 4.8 || ismember(fi,rmem(3,1:K-1)); continue; end
           rmem(:,K) = [C; gama; fi];
    break
  end
   q=0.1073+(100*gama);
  dq=1+(1.34*tan(fi*pi/180)*(1-sin(fi*pi/180)^2));
  Sq=1+(0.5*sin(fi*pi/180));
   Nq = tan((pi/4)+(pi*fi/360)) * tan((pi/4)+(pi*fi/360)) * exp(pi*tan(fi*pi/180));
   Nc = (Nq-1)*cot(fi*pi/180);
   Sc=1+(0.5* Nq / Nc);
     Ngama = 1.5*(Nq-1)*tan(fi*pi/180);
    qult(K)=(1.27*C*Nc*Sc)+(q*Nq*Sq*dq)+(0.13*Ngama);
  end
