Hello:

I am using urlread function to check if particular file exists in a web-page. I have used the following command:

[~, Status] = urlread('https://www.ncei.noaa.gov/data/global-summary-of-the-day/access/1981/01001099999.csv')

Even if the file exists in the webpage, 'https://www.ncei.noaa.gov/data/global-summary-of-the-day/access/1981/', the Status shows 0. Webread cant give the file status. Kindly help!

It works for me in R2019b. If you're trying to do certain things in very old versions, you may find that either some certs or java settings are out of date.

The way urlread() is called silenced any error messages, so we're blind as to why it was failing. If it's still necessary to try troubleshooting, it would help to know what version that was and what the suppressed error message is. If you call urlread() fewer than two outputs, it will dump an error message.
