this is code of my equation getting from you.
Z = zeros(size(W1)); kernel = [Z, W1, Z; W3, Z, W4; Z, W2, Z]; filtered = conv2(vk, kernel, 'same'); vk = (1-w)*vk + filtered./W(i,j);
my equation
v(i,j))^(k+1)= (1-ω)(v(i,j))^(k)-ω[(W1(i,j)(v(i+1,j))^(k)+ W2(i,j)(v(i-1,j))^(k+1)+ W3(i,j)(v(i,j+1)^(k)+ W4(i,j)(v(i,j-1))^(k+1)(/(W i,j)]
v matrix
k iteration
W matrix
w constant
the error I have is!.
Undefined function or variable "vk".
Error in ==> SOR at 69 filtered = conv2(vk, kernel, 'same');

vk is presumably your original signal. If you don't know what it is, then what do you think you're filtering? Why are you attempting to filter something but don't know what it is? If you're running a filter, you must have some idea of what you want to filter, otherwise, why bother?
