[Trilinos-Users] Conversion from Teuchos::Array to Epectra_Vector

Since you are using Teuchos::Array, I would assume that the data is not
too large. In that case, I would simply write it to a ASCII text file;
MATLAB loads these very easily.

I would loop over all of the elements in the array:
ofstream out("data.txt")
for (int i=0; i < array.size(); ++i) { out << array[i] << endl; }

Then, in MATLAB, simply load the file:
array = load('data.txt');
