I want to compute the average of distances between a column and other columns in a matrix except itself.
I'm not sure that the if section is true or not.
the data matrix is nXm size
I'll be grateful to have your opinion.
for i=1:m
for j=1:m-1
if(i==j)
t=0
else
t=pdist2(data(:,i),data(:,j),'jaccard');
b=sum(t)/(m-1);
end
end
end
plot(b)

Use the debugger to step through your code line by line and see what happens. That's how I would find out.
The debugging tools are one of the points where Matlab crushed the competition by GNU Octave, so you should really learn to use them.
