My code is generating this error " Index exceeds matrix dimensions" . Apparently it looks fine. Still can not figure out the problem.

c1 = 0.1;
c2 = 0.0001;
L = 5.0;
M = 0.04;
P1 = 1.0e-2;
P2 = 1.0e-5;
for i=1:64
for j=1:64
C1(i,j) = c1 + P1*(0.5-rand);
C2(i,j) = c2 + P2*(0.5-rand);
end
end
for i=1:64
for j=1:64
dfdC1(i,j) = (L/M) - M*(log(1 - C1(i,j) - C2(i,j)) - log(C1(i,j)))/M;
end
end

dfdc1(i,j) = (L/M) - M*(log(1 - c1(i,j) - c2(i,j)) - log(c1(i,j)))/M;
c1 and c2 are defined as single values (0.1 and 0.0001), but you are trying to index them. I am assuming you want to refer to C1 and C2.
dfdc1(i,j) = (L/M) - M*(log(1 - C1(i,j) - C2(i,j)) - log(C1(i,j)))/M;

I wish Matalb offers an intellegent code analyzer which can recommend these kind of issues and can present alternate solutions as well.
