Dear S_PLUS users,
let me ask you the following question:
given two square matrices A and B ( whose dimension could differ from each
other ), is it possible to create automatically a matrix, let us call it C (
of dimension dimension(A) + dimension(B) ), of the form:
A 0
0 B
i.e. where A and B are the diagonal blocks of C and 0 elsewhere else ?
grateful for the eventual help
Stefano
