Require Matlab coder to assist with one script

Working on a script for non-commercial use by mainly HAM radio enthusiasts and academics etc. and my own interest.

My short script will take 77 precomputed binary bits (MB=[0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 0 0 0 1 0 1 1 0 0 1 0 1 0 1 0 1 0 1 0 1 1 0 1 0 1 1 1 1 1 0 0 0 1 0 0 0 1 0 0 1 1 0 0 0 0 0 1 0 0 1 ...]) and a 14 bit CRC to give 91 bits according to the open source FT8 protocol for low power digital modes designed by Joe Taylor and Steve Franke. Parity and synch bits are added to yield174 bits which are then converted to 58 channel symbols. These channel symbols are then sent to a radio transmitter.

I am stuck on the part where 14 bit crc is added. I am too embarassed to ask former lecturers and colleagues and am sure it is a simple thing but can't work it out. The crc I get is incorrect. The crc I should get is :

[1 0 1 0 0 1 1 0 0 1 0 0 0 0 ] which is reverse engineered from the final channel symbols whch are:

CS=[3 1 4 0 6 5 2 0 0 0 0 0 0 0 0 1 0 6 5 6 3 6 2 3 7 4 1 0 5 4 0 3 2 3 2 1 3 1 4 0 6 5 2 0 1 3 4 5 3 7 3 0 6 3 1 2 1 6 4 1 4 5 4 0 2 3 5 1 3 7 5 5 3 1 4 0 6 5 2 ]

Built in Matlab functions and other scripts I have tried do not give the correct crc either. The original source code for FT8 is written in Python and Fortran which I am not profficient in.

Are you able to solve this simple task and what would this cost? I would credit the coder in any scripts that I publish. My script so far is attached here. Many Thanks
