{{ row.typeTitle }}: ( )

Since our index often lack the full first name of people it can be difficult to correctly search by author.

Fill in the fields and let us help you build a good query:

If you need to find everything possible, consider only searching by last name.

The Methods of Cyclic Reduction, Fourier Analysis and the FACR Algorithm for the Discrete Solution of Poisson's Equation on a Rectangle

Swarztrauber, Paul N.

Siam Review — 1977, Volume 19, Issue 3, pp. 490-501

The methods of cyclic reduction and Fourier analysis are reviewed together with the FACR algorithm which combines the two methods. It is shown that the asymptotic operation count of the FACR algorithm for an n × n grid is O(n2 log2 log2 n) which compares with O(n2 log2 n) for either cyclic
