Hello,
How I can compute in R the orthogonal complement of one matrix?
If A (n x m ) matrix of full column rank (n>m), its orthogonal
complement is denoted by A_ .
A_ is n X (n-m) matrix of full column rank and such that A'A_=0.
I need to compute A_. How I can compute A_ in R?
Best Regards,
/Florin
