array-math 

A library of linear algebra routines

Description

  The array math routines are a part of the Compaq Extended Math Library
  (CXML). This includes a set of standard mathematical functions operating on
  an array. On superscalar architectures, operating on an
  array of data provides significantly better performance than a loop of
  scalar operations.

  The following routines are included in array-math. The Subprogram Name is
  the name of the manual page containing documentation on the subprogram.

       Subprogram Name   Operation

       vsqrt

                         Calculates, in double-precision  arithmetic, the
                         square root of N elements of a vector.

       vcos

                         Calculates, in double-precision  arithmetic, the
                         cosine of N elements of a vector.

       vsin

                         Calculates, in double-precision  arithmetic, the
                         sine of N elements of a vector.

       vrecip

                         Calculates, in double-precision  arithmetic, the
                         reciprocal of N elements of a vector.

       vlog

                         Calculates, in double-precision  arithmetic, the
                         natural logarithm of N elements of a vector.

       vexp

                         Calculates, in double-precision  arithmetic, the
                         exponential function of N elements of a vector.

       vcos_sin

                         Calculates, in double-precision  arithmetic, the
                         sine and cosine of N elements of a vector.
