Subscript indices must either be real positive integers or logicals and other error.

Hi,

I want to read through both matrixes seq and seq2 but gives me two errors. Here is the code:

tr = [0.95,0.05;
             0.10,0.90];

       e = [1/6,  1/6,  1/6,  1/6,  1/6,  1/6;
              1/10, 1/10, 1/10, 1/10, 1/10, 1/2;];

         seq1 = hmmgenerate(100,tr,e);
         seq2 = hmmgenerate(200,tr,e);
         seqs = {seq1,seq2};
         [estTR, estE] = hmmtrain(seqs,tr,e);

pStates = hmmdecode(seqs,tr,e);

Error using hmmdecode (line 96)
The sequence must be numeric, or you must specify the symbols used in the sequence.

   pStates = hmmdecode(seqs(i,:),tr,e);
  Subscript indices must either be real positive integers or logicals.

It seems like you want to call the function hmmdecode(), but you have created a variable with the same name. Check this by:

dbstop if error

Then start the code and wait until Matlab stops. Then type in the command line:

which hmmdecode -all

I know what's the problem. Seqs is a cell and hmmdecode only accepts numeric. Is there a way how to make a loop in seqs to read seq1 and seq2?

please refer to question since it may solve my problem:

I see that you have copied the example right from the documentation. We need to ask, though, which MATLAB version you are using, as you might be using an earlier version that does not support that example as-is.

Have you tried passing in a Symbols name/value pair?
