A. Introduction

This document contains information about the Forte[tm] Developer 7 Math Libraries. This document describes the new features and software corrections that are introduced in this release and lists known problems, limitations, and incompatibilities. Information in this document updates and extends information in the software manuals.

Information in the release notes updates and extends information in all readme files. To access the release notes and the complete Forte Developer documentation set, go to the documentation index at file:/opt/SUNWspro/docs/index.html.

Note - If your Forte Developer 7 software is not installed in the /opt directory, ask your system administrator for the equivalent path on your system.

 

B. About the Forte Developer 7 Math Libraries

This release of the Forte Developer 7 Math Libraries is available on the Solaris[tm] operating environment (SPARC[tm] Platform Edition) versions 7, 8, and 9.

For information on using the math libraries provided with Forte Developer 7 and Solaris 7, 8, and 9, see the Numerical Computation Guide or the section 3m man pages.

 

C. New and Changed Features

This section describes new and changed features for the Forte Developer 7 Math Libraries. For information about other Forte Developer components, see the What's New manual. To access this manual on your local system or network, go to file:/opt/SUNWspro/docs/index.html. You can also access this manual by going to http://docs.sun.com.

Vector Square Root and Reciprocal Square Root Functions Added

The vector math function library, libmvec, contains the following new functions:

Double Precision Single Precision
vsqrt vsqrtf vector square root
vrsqrt vrsqrtf vector reciprocal square root

The vector square root functions compute the square root of each element of the input vector. The vector reciprocal square root functions compute the reciprocal of the square root of each element of the input vector. For each of these functions, the error in each computed result is less than one unit in the last place. (Note that the vector square root functions need not deliver correctly rounded results, unlike their scalar counterparts.)

In this release, the compiler does not automatically transform code that calls the scalar square root functions to use the vector functions when the -xvector flag is used. To use these functions, a program must invoke them explicitly. See the libmvec(3M) man page for more information.
