I have tried with different image, hope you facing the same issue. If not, let me know the size of y?
In the code so many nesting custom functions are there. In the following statement
y = [y; sqrt(y(1:L,:).^2+y(L+[1:L],:).^2)];
From the workspace L=128, but the size of the y is
>> size(y)
ans =
96 200
Then if the indexing is y(1:L,:) that means y(1 to 128, all colm element), where no 128 row in the y, definitely it shows error.
Note and Hints: Debug the code in simmilar way by breaking the above y statement in smaller parts, problem will be resolved.
Say
y1= sqrt(y(1:L,:).^2+y(L+[1:L],:).^2); % Break this line also in y1=y11+y12, do the debug one by one
y=[y;y1]
Hope it Helps!
