im using version 2015a
[xInit, ~] = find_init_sol(y,h,'MMSE',sigma,'64QAM');
[xHatTS, ~] = TS_real(y, h, m, P, '64QAM', Nt, xInit);
x_hat1 = xHatTS(1);
x_zfmod1 = qamdemod(x_hat1,M,'gray'); %%this line they show me INI_PHASE must be a real scalar.

The current documentation for qamdemod function doesn’t use INI_PHASE and since you are using a previous version, you should be referring to the documentation for your version, not for current versions. https://www.mathworks.com/help/releases/R2015b/comm/ref/qammod.html
