How to use webread to download numerical data

3 views (last 30 days)
Hello. I have data in the form of .mat files in a folder in my Boxnet account. I would like to use a Matlab script to read those .mat files. One of those files is A0#.mat. When I use InternetExplorer to open my Boxnet folder I see
https://app.box.com/folder/3917214121
so I assume that is the link to the folder containing A0#.mat.
I have tried
url='https://app.box.com/folder/3917214121';
webread(url);
which does not give me an error but it also does not give any data.
I have tried
url='https://app.box.com/folder/3917214121/A0#.mat';
webread(url);
which gives me an error. Could someone suggest what I am doing incorrectly. Thanks.

I am still trying to access data in a Boxnet folder. I notice in the "help webread" example there is the following:
api = 'http://climatedataapi.worldbank.org/climateweb/rest/v1/';
url = [api 'country/cru/tas/year/USA'];
When I run the example, it works but when I try to use Internet Explorer to go directly to http://climatedataapi.worldbank.org/climateweb/rest/v1/
I get a "not found" error. Therefore, could someone explain what 'country/cru/tas/year/USA' does or what it is?
Thanks.

With [api 'string'] you are concatting the two strings into:
This address is valid and a `webread('http://climatedataapi.worldbank.org/climateweb/rest/v1/country/cru/tas/year/USA')` should return you a 112x1 struct.

Most likely your missing your credentials:
options = weboptions('Username','jdoe','Password','mypassword'); webread(url, options);
See https://ch.mathworks.com/help/matlab/ref/weboptions.html for more details.
