I am trying to simulate the following codes:

data = randi([0 1],100,1);
bpskModulator = comm.BPSKModulator;
bpskModulator.PhaseOffset = pi/16;
modData = bpskModulator(data);
scatterplot(modData)

but I am getting this error: Array formation and parentheses-style indexing with objects of class 'comm.BPSKModulator' is not allowed. Use objects of class 'comm.BPSKModulator' only as scalars or use a cell array.

Error in testerr (line 4) modData = bpskModulator(data);

Can someone help me please?

data = randi([0 3],nframes*numData,numSym,numTxAnt);

modData = qpskMod(data(:));

modData = reshape(modData,nframes*numData,numSym,numTxAnt);

errorRate = comm.ErrorRate;

when i am trying to excute this i am getting Array formation and parentheses-style indexing with objects of class 'comm.QPSKModulator' is not allowed. Use objects of class 'comm.QPSKModulator' only as scalars or use a cell array.

i am getting error in 2nd line can someone assist me please.
