You could also consider the rgb2gray function.

May be, is this to add all channels value to get the particular value
#See Whats going on, same code, just be one line see the Rik's Comments (Prefer & Recommended)
data=imread('1.jpeg');
[r,c,ch]=size(data);
for i=1:r
for j=1:c
data1(i,j)=sum(data(i,j,1:3));
end
end
imshow(data1,[]);

Or just:
data1=sum(data,3);
