I have a 3XN matrix representing a list of 3D coordinates,something like
3XN
33 33 33 33 34 34 34 34 34 35 35 17 18
you mean like this?
D=[33 33 33 33 34 34 34 34 34 35 35; 17 18 19 20 16 17 18 19 20 16 17; 10 10 10 10 10 10 10 10 10 10 10 ]; A=[1 2 3]'; C= bsxfun(@plus, D, A) C = 34 34 34 34 35 35 35 35 35 36 36 19 20 21 22 18 19 20 21 22 18 19 13 13 13 13 13 13 13 13 13 13 13
