M = 128; % Modulation order (alphabet size or number of points in signal constellation)
k = log2(M); % Number of bits per symbol
n = 30000; % Number of bits to process
sps = 1; % Number of samples per symbol (oversampling factor)
rng default;
dataIn = randi([0 1],n,1); % Generate vector of binary data
stem(dataIn(1:40),'filled');

30000 bits
7 bits per symbol
--> 30000/7 = non-integer number of symbols, i.e., you cannot reshape dataIn into a matrix of symbols
