I've tried reproducing this example: https://fr.mathworks.com/help/matlab/ref/matlab.net.http.requestmessage.send.html but get an 'Error using strjoin' message. Any help in tracking down what I'm doing wrong is much appreciated.
>> request = matlab.net.http.RequestMessage;
>> uri = matlab.net.URI('https://www.mathworks.com/support/contact_us');
>> resp = send(request, uri)
Error using strjoin
Unsupported input: string
Error in matlab.net.URI/get.EncodedPath (line 514)
str = strjoin(path, '/');
Error in matlab.net.URI/string (line 680)
path = obj.EncodedPath;
Error in matlab.net.URI/char (line 696)
str = string(obj);
Error in matlab.net.http.RequestMessage>getProxySettings (line 2133)
proxyInfo = matlab.internal.webservices.getProxyInfo(char(uri));
Error in matlab.net.http.RequestMessage/send (line 405)
[proxyURI, username, password] = getProxySettings(createURIFromInput(uri));

It looks like your version of MATLAB is too old and doesn't support string types yet. It is recommended to update to the latest version.

Then please check to see if there is an Update that can be installed. Even the same version of MATLAB may have bug fixes in some Updates. At the same time, you can also check whether your strjoin supports string input.

I see thanks, you are right my strjoin does not support string inputs, and got the same error (unsupported input: string) when I tried checking for updates. I will try with a clean re-installation of the latest version. Thanks for your help.
