JLAPACK - compiling LAPACK FORTRAN to Java

摘要

The JLAPACK project provides the LAPACK numerical sub- routines translated from their subset FORTRAw 77 source into class files, executable by the Java Virtual Machine (JVM) and suitable for use by Java programmers. This makes it possible for Java applications or applets, distributed on the World Wide Web (WWW) to use established legacy numeri- cal code that was originally written in FORTRAN. The trans- lation is accomplished using a special purpose FORTNAN-to- Java (source-to-source) compiler. The LAPACK API will be considerably simplified to take advantage of Java's object- oriented design. This report describes the research issues in- volved in the JLAPACK project, and its current implementa- tion and status.
