You'll probably want to use either interp1() or imresize(). Both are illustrated in the demo below:
clc;
clearvars;
y2 = rand(1, 9385);
y5 = rand(1, 37508);
% The easiest method, using imresize().
% Make y2 the same size as y5
y2Larger = imresize(y2, size(y5));
% Now sum them
output = y2Larger + y5;
% Alternative method using interp1
x = linspace(1, length(y5), length(y2));
xi = 1:length(y5);
y2Larger = interp1(x, y2, xi)
% Now sum them
output = y2Larger + y5;

Use reshape
Y=function(X,m,n)
It works for any input matrix (X) with number of elements (m x n). The output is Y with m-rows by n-columns. The size of X and Y must be the same.
