Hi all,
I tried to generate MA(1) model without presample. I typed following command.
Mdl= arima('Constant',1.5,'MA',{0.1},'Variance',1.9)
In the command window, the error comes up:
Error using arima
Too many input arguments.
I just referred to this instruction(https://mathworks.com/help/econ/arima.html?searchHighlight=arima&s_tid=srchtitle#d122e112384) and I don't know where I got wrong. Please help me.

2020a. I updated it to 2020b and now it works.
