I want to sample a value from a normal distribution and I wrote down this codes. Can someone please look at it and hint me if it is appropriate. I am Matlab basic user.
r=rand;
ci_l=find(cumu<=r,1,'last');
ci_h=find(cumu>=r,1,'first');
if abs(cumu(ci_l)-r)<=abs(cumu(ci_h)-r)
ci=ci_l;
else
ci=ci_h;
end
cmuO=getCDF(pdfY);
cmuO=cmuO/max(cmuO);
[~,idx]=min(abs(cmuO-cumu(ci)));
newVal=pdfX(idx);

Cumu was created somewhat with code related with makedist().

Is the "YES" intended to mean that Yes, it is a vector sorted in increasing order?
