Hello Experts;
I am new in matlab and trying to learn how we can create function? For Example . I have this code how I can create function file out of it? It will be easy for me to learn from this code.
g=imread('cameraman.tiff');
original=g;
[m,n]=size(g);
subplot(2,2,1)
imshow(g,[])
[m,n]=size(g);
a = 3;
b = 3;
num_iter = 5;
for k=1:num_iter
for i=1:m
for j=1:n
r = mod([round(abs(1-(a*(i^4))+j)),round(abs(b*i))],[m n]);
x(i,j)=g(r(3)+1,r(4)+1);
end
end
g=x;
end
subplot(2,2,2)
imshow(x);

>> x =imread('cameraman.tif');
>> y = x*0;
>> [w h]= size(x);
>> for i = 1:w
for j =1:h
b =bitget(x(i,j),6)
y(i,j)=bitset(y(i,j),6,b);
