generate matrix from submatrices.



Thanks a lot to both ! it saved me. And sorry for late answer, i needed time
to test it.

By the way, is there a way to save the maxima command history into a file ?
i tried save("filename"); but it says that there was a writing error.

I'm using maxima under linux  in console mode.

Thanks & Regards
