Hi Muyiwa,
I understand that you are trying to include the username and password in the code for authentication. I was reading about the same in the documentation, and it looks like you can pass the same in MATLAB R2015b through the “options” object in “matlab.wsdl.createWSDLClient”. This functionality, however, doesn’t seem to be present in the earlier functions of MATLAB. Here is the link that explains the same:

Hope this helps!

This works for creating the WSDL methods, however, this functionality doesn't seem to work when calling the web service. This is stated in the documentation link above -" ...The options also do not apply to requests made to servers by the generated code".
Any ideas how I can work round this? i.e how can i include the username and password in the call
