Dear all,

I do not know how to deal with block matrices in R.

For example I have 3 matrices A, B and C.

And I want to produce a new matrix of this form

( A B 0 )
( 0 0 C )

where A, B and C are one-row matrices.

Apart from A, B and C, all the coefficients are 0.

Is there an easy solution in R for every block matrices ?

Thanks for your help,
Gustave

P.S. : I have had a look at a function called "zoo" which looked quite
complicated to me.
