It is part of my thesis. I need to strictly adhere with 3GPP document to avoid any calibration issues. I am supposed to replicate first phase calibration result as given in TS 38.900 and related document.
If you have an option of doing in NetSim as well, then the
TTS 36.900 features implemented can be seen in https://tetcos.com/5g.html an you can look at section 4.2 in https://tetcos.com/downloads/v12.1/Technology-Libraries/5G-LTE-NR-mmWave.pdf
Select a most relevent paper on TS 38.900 and try to replicate that first un term of results. During this process you will b able to understand things in a better way as well as it will clear your concepts on the given topic. Hopefully, it will give you new ideas to implement 5G channel modeling issues on MTALAB.
the documentation page on the matlab website, gives a good heads up.

furthermore, the 3GPP has a similar algorithm out of the myriads of algorithms presented in the documentation.
