Thank you Duncan, Kjetil and William.
Kjetil, with rep(0,2), I get a vector. So I have to transpose it.
cbind(A,B, t( rep(0,2) ) )
if C is of length 2. Is that right ?
I like very much Duncan's general solution.
Thanks a lot,
Gustave

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

where A, B and C are one-row matrices.
The problem is that mathematica

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
