I have a question: the subspace algorithms are based on the L-Q decomposition of a matrix. Suppose I have 2 matrices to be decomposed for example A1, A2. Is there a way in Matlab to get the decomposition of the matrix obtained by concatenating A1 A2 as
A =[A1, A2]
from the single decompositions?(Especially I am interested in the L matrix). I need this to concatenate the single channel models obtained to have a unique multi channel model of the same order.
If somebody knows a way to concatenate the SISO models obtained with n4sid function to get the multi channel model it would be even better. Thanks in advance
