在 MATLAB Online 中打开

 temp1=cumsum(cl)/sum(cl);
 temp2=cumsum(cr)/sum(cr);
temp3=floor(256*temp1);
temp4=floor(256*temp2);
 a=I;a2=a;
for i=0:255
    if i<m1
        a2(I==i)=m1*temp1(i+1);
    else
        a2(I==i)=m1+(max(I(:))-m1)*temp2(i+1);
    end
 end

Can you provide more information? What random numbers are you working with?

Take a look at all the supported distributions. All the common PDF and CDFs are already available.

numbers you can use like 0:255, http://ieeexplore.ieee.org/xpls/abs_all.jsp?arnumber=580378 is the paper that I am trying to implement but I am sure I am not coding very well, and I think Matlab built in Distribution may not applicable, Infact I Also dont Want to Use MAtlab built-in to build understanding of equations and how to code them, Sorry I am newbie.
