Although it's not open source, Scilab is a free program with
capabilities similar to those of Matlab, including a block diagram
modeling language. It isn't as polished as Matlab, but it allows (IMHO)
better program structure.
You might also be interested in:
for examples in both Scilab and Python.
That said, I'd still prefer to work in Python, even without a block
