I'm trying to make an app in MATLAB's app designer that pulls values of current exchange rates from online sources, but the url shown below doesn't seem to work for me and I do not know how I would be able to import these values to begin with. The function for getExchangeRate has filler values that I would like to have be replaced with the values that get updated consistently.

% Button pushed function: ConvertButton function ConvertButtonPushed(app, event) USDAmount = app.AmountEditField.Value; selectedCurrency = app.CurrencyDropDown.Value; exchangeRate = getExchangeRate(selectedCurrency); convertedAmount = USDAmount exchangeRate; app.Label_2.Text =sprintf(%0.2f%s, convertedAmount, select % % % % % % % % % % url = 'https://wWW.x-rates.com/table/?from=USD\&amount=1'; htmlContent = webread(url); currencyPattern = '>span class=" currency-value" >(. ? ) span>' currencyMatches = regexp(htmlContent, currencyPattern, 'tokens usdValue = str2double (currencyMatches {1}{1}); eurValue =str2 double ( currencyMatches {2}{1}); convertedAmount = convertCurrency (app, USDAmount, selectedCurr function rate = getExchangeRate(currency) switch currency case 'EUR ' rate=0.91795; case 'GBP' rate=0.78917; case 'INR ' rate=83.0166; case 'AUD' rate=1.49196; case 'CAD' rate=1.33729; case 'SGD' rate=1.33327; case 'MYR' rate=4.67098; case 'CHF
