Hi,
I am currenty using a 2d array to run some surface propogation algorithms. My current implementation of nested for loops is too time consuming and I heard that parfor can help speed up this task as the update function does not depend on the new output values of the function. Basically my current code is structured as follows:
for i=1:30
for j=1:30
phi(i,j)=f(i,j) %Compute the function value based on the current position
end
end
I was wondering if changing the first for loop to parfor will retain the functionality of my code:
parfor i=1:30
for j=1:30
phi(i,j)=f(i,j) %Compute the function value based on the current position
end
end
Is this a correct implementation of a parfor loop for my implementation?

Hi Ammar,
As you've written, yes, this will work fine. Reference this doc for any troubleshooting.
