Find the higher frequency for nearest value in column

Dear Colleagues, Could any body help me in the bellow code

x=[119.499;-0.192;-0.008;0.006;-0.398;-0.046;-0.028;0.104;-0.019;-0.003] In my matrix x, I want to retrieve the value which is higher in frequency with their nearest value. For instance, no value is duplicated, so the common value in my matrix to be closest with most of values

 [X1 X2] = meshgrid(x, x');
 D = sqrt((X1 - X2).^2);
 x_closedtoall = X1(1, find(sum(D) == min(sum(D))))
