Most people do not know the toolbox or have the url. Posting the url makes it more likely that someone might take a look.
I myself have no idea how that toolbox works.

IRIS is a free, open-source toolbox for macroeconomic modeling and forecasting in Matlab®, originally developed by the IRIS Solutions Team and currently maintained and supported by the Global Projection Model Network.
In a user-friendly command-oriented environment, IRIS integrates core modeling functions (including a flexible model file language with a powerful preparser, a variety of tools for simulation, estimation, forecasting and model diagnostics, practical techniques for judgmental adjustments, and more) with supporting infrastructure (such as data management, time series analysis, and reporting).
Here, is the toolbox main page

and here is the toolbox itself

Use function convert
m_ts = tseries(mm(1990,1):mm(2020,12),rand(1,372));
q_ts = convert(m_ts,'q')
convert accepts parameters to change the conversion type
