how can I use webread with comma in URL: e.g. my call: > url = 'page.html?q=1,2,3'; resp = webread(url);

Using webread this encodes to : page.html?q=1%2c2%2c3 and the server I'm calling returns an error (I have no control over that service and cannot change its API). There is much information about URI encoding, for example here: http://stackoverflow.com/questions/2366260/whats-valid-and-whats-not-in-a-uri-query But it doesn't help with Matlab's webread. Do you know what I need to do so that it passes a comma ","?

在 MATLAB Online 中打开

That's because those things after the '?' are not really part of the URI, but are query parameters. webread separate these from the base URI. You just specify these query parameters after the base URI as pairs of parameter name and parameter value. In your example:

webread('http://somwhere.com/page.html', 'q', [1 2 3])

Thank you. This works for the above case. However, some APIs don't expect query parameters. I have an API call like this: >url = 'http://somewhere.com/somebranch/4,5';

is there a way for webread to construct this? (apologies if this seems to be a separate question) Again, the problem is the comma.
