Slow "for loop"

[Tommy77]

Hi All,

I am filling a 512x512 array using a couple of for loops which is really slow. I have an initialized array outside and I am using the "replace array subset" as I have heard that this is the fastest way of doing it. In the picture there is an outer third loop which is just the number of arrays to be filled but as it takes 1-2 minutes to complete the inner 2 loops the uoter loop is not the problem.

Any help would be most appreciated.

Thanks

Hi Tommy77,

it'll not solve the speed problem, but you definitively need shift registers.

Can you upload your vi?

Now i haven't tried this myself, but you've disabled indexing of the matrix. Isn't the whole idea to use the autoindex to make it easier to replace?
