R is not so easy to use for big matrix computations? This is a first for me. R is extremely efficient at dealing with matrices. If you have huge matrices, I don't think it would perform much better than anything else. If you need sparse matrix functionality, R comes with it built in. Python is actually horrible for mathematical computations since it basically runs everything in FORTRAN and C. The overhead to manipulate the data to call these libraries is enormous. R might actually be doing the same. Matlab does this as well.
Honestly, what I have found is that printing tables and results is best done by manually coding latex using booktabs and three part table. It isn't that hard to do either. Write your results as a CSV and if you are good at scripting, just separate the csv from the data frame into rows. Add a header and you are good to go. This way, any time you have a CSV, you can easily get it into tabular format and all you have to do is specify the header and footer, something that is notoriously difficult to automate. Trust me, I have tried a dozen or more times and it never just works. ~Ben On Sun, Jan 25, 2015 at 3:35 PM, Steve Burnham <dan...@gmail.com> wrote: > There is a package on CTAN called pythontex that allows you to run python > from within a document.
