Time series properties error

I am trying to re do the following tutorial but i don't use datafeed toolbox to get Quandl data. I use the Quandl package directly.

https://www.mathworks.com/videos/machine-learning-applications-in-risk-management-forecasting-bitcoin-volatility-using-the-regression-learner-app-1536231842528.html

I have the following code and error.

THE CODE:

Connect to Quandl

Load credential and connect to Quandl

c = Quandl.api_key('xxxxxxxxxxxxxxx'); % You need to enter your Quandl key here

%c = quandl(quandlKey);

clearvars quandlKey

Set symbols for retrieving data

symbol1 = {'BCHAIN/MKPRU', ...% Bitcoin Market Price USD

'BCHAIN/MWNUS', ...% Bitcoin My Wallet Number of Users

'BCHAIN/DIFF', ...% Bitcoin Difficulty}; % Total Bitcoins

Retrieve data from Quandl in the past 2,000 days

nDays = 2000;

d = cell(1,numel(symbol1));

d{1} = Quandl.get(symbol1{1}, today - nDays,today - 1);

T = d{1};

for i = 2:numel(symbol1)

d{i} = Quandl.get(symbol1{i}, today - nDays,today - 1);

T = synchronize(T,d{i});

end

Create new variable names

symbol2 = regexprep(symbol1,'BCHAIN/',''); % Tighten symbols' name

T.Properties.VariableNames = symbol2;

THE ERROR:

no appropriate property , method or field 'properties' for class 'timeseries'

Hey

The error you're encountering occurs because the synchronize function is expecting input tables or timetables, but the Quandl.get function might be returning timeseries objects.

To fix the error, you can convert the timeseries objects to timetable before using the synchronize function.

Adding MATLAB documentations that will help you resolve the error:
