MATLAB: Binning with nested for and if/else loops

Question

Hello all, I am trying to take a very long vector of distances and bin it. I'm indexing both the vector and a vector if bins. Currently the code returns all zeros, even though the distance bins should range from 0-165 (cm).

The basic idea is as follows: If a distance value is >=165 (for example), that value is then replaced with '165' (its bin). Same for every value down to 0.

If I did nested if/else, I understand that if/else stops once it meets a true condition, but I don't want to write if/else 34 times (the number of bins I have). Hence the indexing.

Here is my code. Can anyone tell me what I'm doing wrong?

=============================

bin=[164 158 142 122 108 97 67 44 28 10 6];

DistBin=[165:-5:0];

for BinIndex=1:length(bin);

    for DBIndex=1:length(DistBin);
        if bin(BinIndex) >= DistBin(DBIndex);
            bin(BinIndex)=DistBin(DBIndex);
        else 
        end
        end
    end

==================================

If I try to add an "else" statement to keep it stepping forward (as below) I get the same result.

==================================

bin=[164 158 142 122 108 97 67 44 28 10 6];

DistBin=[165:-5:0];

for BinIndex=1:length(bin);

    for DBIndex=1:length(DistBin);
        if bin(BinIndex) >= DistBin(DBIndex);
            bin(BinIndex)=DistBin(DBIndex);
        else bin(BinIndex) >= DistBin(DBIndex+1);
            bin(BinIndex)=DistBin(DBIndex+1);
        end
        end
    end

Can't you just histogram it with hist() or histc()???
