Recently I installed student version of MATLAB and Communication System Toolbox (R2019a). I am finding the functions ldpcenc() and ldpcdec() to be missing. Is this expected? Or am I supposed to see all the functions even in the student version?

Yes, the Student Version has access to all of the same functions. The Student Version has the restriction that Simulink models can contain no more than 1000 blocks, and that reports will have a watermark "Student".

I am finding the functions ldpcenc() and ldpcdec() to be missing. Is this expected?

Yes, it is expected. The Communications toolbox has never had functions of that name.

R2006b introduced fec.ldpcenc . R2012b introduced comm.LDPCEncoder and R2016a removed fec.ldpcenc

If you look at the example https://www.mathworks.com/help/comm/ug/estimate-ldpc-performance-in-awgn.html you will see that it starts

ldpcEnc = comm.LDPCEncoder;
ldpcDec = comm.LDPCDecoder;

Notice that ldpcEnc or ldpcenc are not functions of their own: they are variables that have been assigned something.

To supplement Walter's answer, the Communications Toolbox Release Notes specifically suggest comm.LDPCEncoder as the replacement for fec.ldpcenc and similarly for comm.LDPCDecoder and fec.ldpcdec.
