This clip fom the command window summarizes my question. I hav a new install of MATLAB 2022a on MacOS 12.4. Has something changed?
>> bytes = [0x57 0x58 0x53 0x54]
bytes =
1×4 uint8 row vector
87 88 83 84
>> str = ascii2str(bytes)
Unrecognized function or variable 'ascii2str'.

Ran in:
According to the documentation "The operator ascii2str is supported only in Stateflow® charts that use C as the action language."
In MATLAB the equivalent is the char function.
bytes = [0x57 0x58 0x53 0x54]
bytes = 1×4
87 88 83 84
c = char(bytes)
c = 'WXST'
