I tried to implement the Strassen's algorithm for big matrices multiplication in R.
Here I present a pdf with some theory element, some example and a possible solution in R.
I'm not a programmer, so the function is not optimize, but it works.
I want to thank G. Grothendieck: suggested me a very nice way on StackOverFlow to create a bigger square matrix starting from small one.
This is just a first version of the function; it needs more work on it. If someone want to collaborate, I'll be very happy.
Finally if you find my code useful for your work, I'd love to be cited (ask me via e-mail how to cite me: todoslogos -at- gmail . com).
