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.
