[Maxima] is a Free and Open Source mathematical language running on a [LISP] interpreter for which there are [Tcl] bindings and a [Tk] interface, I've a few pages on how to use it with tcl, and in this case I'd like to make maxima formulas, for instance for signal processing, into a graph by using tcl and maxima combined.

An example formula is an addition of variables and numbers, like:

  output = in1 + (3 + in2)

for no particular reason, in this example, which could be seen as a single bwise block with three inputs and one output, the main operator is addition. Of course this is often the case, but a random mathematical function or formula (lets assume with one output or result or result variable) often as an addition as top level operator.

What I'd like to do, and automatically too is to make blocks for each level of the formula evaluation, in the above case in1 +() and 3+in2. 

In Tcl I did something of the kind once ([constructing a bwise graph from a formula]), but I didn't like it enough, so I don't go into that, but I want to do some work on getting a random maxima formula correctly decomposed in blocks. I can already do the converse at "string=formula" level with substitutions.

The idea is to use a maxima formula deconstruction function, repeatedly driven from tcl and than have bwise automatically create and place the blocks.
