I tried sum(vect1,vect2) and a lot of other ways but I cant get the answer. for example vect1 is a column vector that contains even numbers from 200 to 220 and vect2 contains elements 0:0.1:1 ... Following is what I have so far but after Displaying the lengths of both vectors. I am unable to display the elementwise sum of the two vectors (first element in vect1 is added to first element of vect2, second element to the second etc.) in the form of a row vector
vect1 = (200:2:220)';
vect2 = 0:0.1:1;
vect2 = vect2 * 40;
length(vect1)length(vect2);

vect3 = vect1.'+vect2
If you want to be sure of the element by element sum, regardles the shape of the two vectors (row or column), with the assumptions they are of the same length, you can force them to be column vectors and then transpose the result
vect3 = (vect1(:)+vect2(:)).'
