Numerically good null spaces

There are many meth­ods to obtain null vec­tors to a given set of vec­tors. One of the numer­i­cally best meth­ods is imple­mented in MATLAB, based on sin­gu­lar value decom­po­si­tion, SVD. Null vec­tors can be used for many dif­fer­ent things; one of them is to remove prop­er­ties that are ore orthog­o­nal to another, given prop­erty. Such …
