**Wrapping numerical libraries**

[AM] As mentioned on the [Tclode] page I have been playing with the idea to wrap a lot of existing numerical libraries (some written
in the venerable FORTRAN 77 programming language, others in C). For C we have [Critcl] to facilitate the wrapping, for FORTRAN we can
use my Wrapfort (in my [ftcl] project on SourceForge [http://ftcl.sf.net]). The problem with many of these libraries is not so much the
wrapping in itself, but the design of the interface.

For example, wrapping the LAPACK library (see [wrapper extension for LAPACK]) is a lot of work because there are so many routines.
However, a lot of it can be automated (I have done that part already). The next step is to make the interface Tclish enough:
The routines require the dimensions of arrays to be passed explicitly. If you map Tcl lists to arrays (or use byte arrays for efficiency), 
then the dimensions can be deduced from the data. So the interface exposed by the wrapper can be simpler.

A second part of the work is to package the source code with appropriate make files
