The physunits toolbox is an attempt to confer dimensional "awareness" to the MATLAB environment. The motivation for this, as well as a suggested way to go about it, are explained in
% Petty, G.W., 2001: Automated computation and consistency checking of
physical dimensions and units in scientific programs. Software -
Practice and Experience (Volume 31, Issue 11, 19 June 2001)
The author of the same has also made available for download a FORTRAN90 module that implements this ides in the FORTRAN language. The module and paper can be downloaded from
http://rain.aos.wisc.edu/~gpetty/physunits.html
The physunits toolbox is based on the above module, and expands it, while trying to adhere consistently to MATLAB standards and practices.
The zip file contains:
@preal (directory) -
In MATLAB, classes are defined by a directory of the class name preceded by a @ sign. The @preal directory contains the preal class definition and methods. To use the preal class, the directory IMMEDIATELY ABOVE @preal should be added to the MATLAB path.
setUnits.m -
MATLAB .m file with predefined units and constants. See documentation for usage.
info.xml - Pointer to the html documentation file. Used by the MATLAB
help browser.
html (directory) -
Containing the html help and documentation files.
physunits.m - a function for switching the physunits on or off.
iceball.m - a short sample program that demonstrates the preal class. |
