I am not sure, what value is needed for "Q". One in code is giving me error saying "Subscript indices must either be real positive integers or logicals."

Firstly, as far as the error is concerned, to access any element of an array, its index has to be an integer, not a real number (which is according to your code). Secondly, why do you have to define a separate array for Q , instead use function * qfunc()* to compute CDF of the random variable.

Using qfunc() giving same error.

why do you require x? you already have defined EbNo array ,i.e., 0:10. As far as theory goes, BER = Q(sqrt(Eb/No)). Just use qfunc(sqrt(EbNo)). NOTE : as far ar error is concerned, see my last reply.
