Illegal use of reserved keyword "end".

[Gurpreet]

why error Illegal use of reserved keyword "end". is coming
f=imread('5.jpg');
[r,c]=size(f);

fg(r+5,c+5)=0;
fg=f;
y=0;
for i=1:r
for j=1:c
for k=1:5
for l=1:5
y(i,j)=y(i,j)+(a(i,j) + fg(k,l)/(1+exp(-(fg(i,j)-fg(k,l))/25))/{a(i,j)/(1+exp(-(fg(i,j)-fg(k,l)))/25)
end
end
end
end

It appears that you have a curly brace in there just before the a(i,j)
for some reason. Probably should be a round parenthesis. Also, when
I pasted your code into another program, it's showing a hidden
character between the 2 and the 5 of the last 25 in your equation.

i haven't checked it all but in the y()= equation there is an unmatched {
