Hi,
I tried to download data with getFredData and this Error message kept coming up:
Error using xmlread (line 116)
Java exception occurred:

I have read the previous thread and tried to add pauses. But obviously my error code is different and it didn't solve the problem. Besides, I tried to use different item codes for the Real GDP. The code I am using in this trial was drawn from the given example. I wonder if anyone can give a hint on what went wrong and how I can possibly solve it. Thank you in advance!
Output argument "val" (and maybe others) not assigned during call to "getFredData>getValue".
Are these functions just busted? Every time I try to use them Matlab also crashes like 5 minutes later.
Hi,
Thank you very much for sharing this nice code. I am trying to use loop to get ALFRED data using your function. At some point in the loop, I get error message like below. When I manually execute the command at that point, it does work. Can I ask why this happens? Is it because of I am extracting data from the server too fast?
