MATLAB: Distance between all elements of row vector

distance

So, I have 1×200 matrix, (row vector). I want to find difference (x(0)-x(1), x(0)-x(2)…) between all elements of an array. How do I do that ?
I should be having 200×200/2 values.

Hint:
%%
row = rand(1,6);
cell2mat( reshape( arrayfun( @(jj) row(jj)-row, (1:6), 'uni', false ), [],1 ) )
outputs
ans =
         0   -0.0790   -0.0644    0.2865    0.0233    0.5075
    0.0790         0    0.0146    0.3655    0.1023    0.5866
    0.0644   -0.0146         0    0.3509    0.0877    0.5719
   -0.2865   -0.3655   -0.3509         0   -0.2633    0.2210
   -0.0233   -0.1023   -0.0877    0.2633         0    0.4843
   -0.5075   -0.5866   -0.5719   -0.2210   -0.4843         0
