that codes are 2015 version
hmodem = modem.qammod('M',M, 'SymbolOrder', 'Gray','InputType', 'bit');
hdemodem = modem.qamdemod('M', M,'SymbolOrder','Gray','OutputType','bit');
digMod1 = modulate(hmodem,x(Nt+1:Nt+Nobit,:));
digMod2 = modulate(hmodem,x(Nt+Nobit+1:Nt+2*Nobit,:));
bitb1 = demodulate(hdemodem,sqrt(42)*ytry(inth(1)));
bitb2 = demodulate(hdemodem,sqrt(42)*ytry(inth(2)));
i want to change these codes 2020 version

The modem package was removed from Communications Toolbox in release R2019a. We first noted that modem.qammod and modem.qamdemod would be removed in a future release starting in release R2016a and we started issuing warnings about all the functionality in the modem package being removed in release R2018a. See the table in the Release notes for recommended replacements for those functions.

hmodem = modem.qammod('M',M, 'SymbolOrder', 'Gray','InputType', 'bit');
digMod1 = modulate(hmodem,x(Nt+1:Nt+Nobit,:));
digMod2 = modulate(hmodem,x(Nt+Nobit+1:Nt+2*Nobit,:));
should be replaced with
digMod1 = qammod(x(Nt+1:Nt+Nobit,:), M, 'gray', 'InputType', 'bit');
digMod2 = qammod(x(Nt+Nobit+1:Nt+2*Nobit,:), M, 'gray', 'InputType', 'bit');
and
hdemodem = modem.qamdemod('M', M,'SymbolOrder','Gray','OutputType','bit');
bitb1 = demodulate(hdemodem,sqrt(42)*ytry(inth(1)));
bitb2 = demodulate(hdemodem,sqrt(42)*ytry(inth(2)));
should be replaced with
bitb1 = qademod(sqrt(42)*ytry(inth(1)), M, 'gray', 'InputType', 'bit');
bitb2 = qademod(sqrt(42)*ytry(inth(2)), M, 'gray', 'InputType', 'bit');
