Description
The function makes a block diagonal matrix from quadratic blocks (potentially of different sizes) along the diagonal of a given matrix X.
Usage
1
make.bdiag(X, indexvec)
Arguments
X
A quadratic matrix.
indexvec
A vector of indices that describe where the quadratic blocks end.
Details
Block 1 is X[1:indexvec[1], 1:indexvec[1]], block 2 is X[(indexvec[1]+1):indexvec[2], (indexvec[1]+1):indexvec[2]], etc.
Value
A sparse block diagonal matrix of class CsparseMatrix.
