for i=1:n-1
for j=1:n-1
for r=1:332
if i + r > 333
data(i+r,:)=0;
*else if i-r = < 0
data(i-r,:)=0;*
else if j+r > 333
data(:,j+r)=0;
else if j-r = < 0
data(:,j-r)=0;
end
end
end
end
end
end
end
Please tell me how I can correct the error at i-r = < 0

Change the '= <' to '<=' (without the apostrophes.)

Your line s=s+data(i+r,j)+data(i-r,j) is outside of any of your "if" tests, so it is going to always be executed. It will cause a problem if i-r is 0 or negative.

Do you really have a space between the = and the < ? If so, remove it.
Please add the error message. Otherwise we have to guess, what your problem might be.
