Steve on Image Processing

December 11th, 2007

Remembering Gene Golub, 1932 - 2007

The book Matrix Computations by Gene Golub and Charles Van Loan sits on the bookshelves of many MathWorks employees. Professor Golub, one of the founding members of the Stanford University computer science department, is a revered figure in the area of numerical analysis and matrix computations.

We were very sorry at MathWorks to hear that Professor Golub passed away last month at the age of 75. His contributions will live on in modern scientific and engineering computing.
