My Code is :
function Hout = Hcomb(a , b , c)
%%%%% Get the size of Image
[r ,c] = size(a);
for i = 1:r
for j= 1:c
if (a(i,j) > b(i,j)) && (a(i,j) > c(i,j))
Hout(i,j) = a(i,j);
elseif (b(i,j) > a(i,j)) && (b(i,j) > c(i,j))
Hout(i,j) = b(i,j);
elseif (c(i,j) > a(i,j)) && (c(i,j) > b(i,j))
Hout(i,j) = c(i,j);
end
end
end
return;

Error at elseif (c(i,j) > a(i,j)) && (c(i,j) > b(i,j))

One of the input argument is variable 'c' and you use the same name again for the size of variable 'a' and hence gives you an error, try rename them as follows:
function Hout = Hcomb(a , b , c)
%%%%% Get the size of Image
[row ,col] = size(a);
for i = 1:row
for j= 1:col
if (a(i,j) > b(i,j)) && (a(i,j) > c(i,j))
Hout(i,j) = a(i,j);
elseif (b(i,j) > a(i,j)) && (b(i,j) > c(i,j))
Hout(i,j) = b(i,j);
elseif (c(i,j) > a(i,j)) && (c(i,j) > b(i,j))
Hout(i,j) = c(i,j);
end
end
end
return;

works good i forget about variable name

Nothing in this code guarantees that the size of b and c are identical to the size of a. If they aren't the same size, you will end up with errors. Since you didn't reveal anything about what you passed, I'm going to have to assume that's what you did.
