Why do you wish to use for and if for searching the locations of SE? You can use without using for and if, and it would be very quick and short.
R12=randi(15,12,12)
SE=5
[xx,yy]=find(R12==SE);
[xx,yy]
But still if you wish to use for and if, below is the code you can use:
location=1;
for ii=1:size(R12,1)
for jj=1:size(R12,2)
index=R12(ii,jj)==SE;
if index==1
xx_index(location)=ii;
yy_index(location)=jj;
location=location+1;
end
end
end
[xx_index; yy_index]'
Hope this helps.

Yes, that is the logical part. The code gives you the x and y indices of the locations of SE elements in the R12 matrix.
