M. L. Pei [
Comm. ACM 5, 10 (Oct. 1962)] gave an explicit inverse for a matrix of the form
M +
&dgr;I, where
M is an
n-square matrix of ones and
&dgr; is a nonzero parameter. The eigenvalues of the Pei matrix were given by W. S. LaSor …

Some computer operating systems have a bad habit of inserting tape marks into the output stream willy-nilly. This often results in loss of output when a tape is scratched after its first file has been printed. Other operating …

A formula for numerical integration is prepared, which involves an exponential term. This formula is compared to two standard integration methods, and it is shown that for a large class of differential equations, the exponential …

The technique of obtaining arctangents by inverse interpolation [1] is a relatively long process not suitable for a subroutine. The Taylor series expansion for arguments less than unity converges rather slowly for those near
