Currency exchange rates through the web service in MATLAB

How can I get the current exchange rate for two given currencies in matlab?

I tried this one , however it seems that the web service is no longer available.

Is there another easy way to get updated exchange rates through a web service in Matlab?

Create a local class from the currency conversion web service using CREATECLASSFROMWSDL . You can then use the web service operations to convert using class methods. One web-based currency conversion service (there are many) can be found at http://www.webservicex.net/CurrencyConvertor.asmx?WSDL . Here is an example of its use:

>> converter = createClassFromWsdl ('http://www.webservicex.net/CurrencyConvertor.asmx?WSDL');
Retrieving document at 'http://www.webservicex.net/CurrencyConvertor.asmx?WSDL'
>> converter = CurrencyConvertor
    endpoint: 'http://www.webservicex.net/CurrencyConvertor.asmx'
        wsdl: 'http://www.webservicex.net/CurrencyConvertor.asmx?WSDL'

>> ConversionRate (converter, 'CAD', 'EUR')

ans =

0.7059

>> ConversionRate(converter, 'USD', 'CAD')

ans =

0.953
