Cleve’s Corner: Cleve Moler on Mathematics and Computing

Charles Lawson, 1931 – 2015

Posted by Cleve Moler,

Chuck Lawson passed away in July at the age of 83. Chuck was one of the people who introduced me to computing and mathematical software. I worked for him at Caltech's Jet Propulsion Laboratory during the summers of 1961 and 1962, just before and after my first year in grad school.... read more >>

Dubrulle Creates A Faster Tridiagonal QR Algorithm

Posted by Cleve Moler,


Augustin (Austin) Dubrulle deserves to be better known in the numerical linear algebra community. His version of the implicit QR algorithm for computing the eigenvalues of a symmetric tridiagonal matrix that was published in a half-page paper in Numerische Mathematik in 1970 is faster than Wilkinson's version published earlier. It is still a core algorithm in MATLAB today.... read more >>
