Mapping 2 vectors - help to vectorize

Question

Working in Matlab I have 2 vectors of x coordinate with different length. For example:

xm = [15 20 24 25 26 35 81 84 93];
xn = [14 22 26 51 55 59 70 75 89 96         


        

Answer 1

Consider this vectorized solution:

[~, xmap] = min( abs(bsxfun(@minus, xm, xn')) )
