Hi, I need the original code of imquantize function of matlab. Please help.

My attempt:

I=imread('football.jpg');
I=rgb2gray(I);
[M N]=size(I);
T1=91;
T2=150;
for x=1:M
    for y=1:N
        if(I(x,y)<T1)
            I(x,y)=0;
        elseif(T1<I(x,y)<=T2)
             I(x,y)=120;
        else
            I(x,y)=255;
        end
    end
end
 
figure;
imshow(I);
