MATLAB HP 9000/Series 300 dynamically linked subroutine file
File type: Various data file
A MEXHP3 file is a compiled dynamically linked subroutine for MATLAB on HP 9000/Series 300 systems.
It is a platform-specific MATLAB extension file rather than a document intended for direct viewing.

MEXHP3 files belong to MATLAB, the mathematical computing software from MathWorks. They contain dynamically linked subroutines compiled for the HP 9000/Series 300 platform, allowing MATLAB to use compiled code as an extension.
Although MATLAB is available on multiple platforms, this file type is tied to the HP 9000/Series 300 environment and is a legacy format. It is not generally used by current MATLAB installations.
Open a MEXHP3 file only with a compatible historical version of MATLAB running on an HP 9000/Series 300 system. The file is loaded as a MATLAB dynamically linked subroutine, not opened as text or as a standalone document.
Modern MATLAB versions and other operating systems generally cannot load this platform-specific file.
A MEXHP3 file cannot be meaningfully converted to a standard document or data format because it contains compiled platform-specific code.
If the original subroutine source code is available, it can be recompiled for a supported MATLAB platform and interface. Without the source and a compatible historical MATLAB environment, there is no practical conversion method.
