MexEPS for MATLAB

MexEPS is a mex-file interface between EPIC System and MATLAB
which enables MATLAB users to access EPIC System data file
and many other netCDF file conventions, such as those produced
by Ferret, WHOI, etc. efficiently within the MATLAB.

Here is one of the examples which uses MexEPS
function to generate a potential temperature contour plot
from EPIC CTD data files.

MexEPS supports the following data formats:

- NetCDF
data file (read/write/edit)
- Classic
EPIC data file (read/write)
- Generic formatted ASCII
data file (read only)

The function includes VARIABLE manipulation routines, AXIS
manipulation routines, ATTRIBUTE manipulation routines and
TIME manipulation routines. Many styles of time axes are supported
and time manipulation routines ease the use of that axis in
MATLAB. TIME enters MATLAB on read as YYMMDDhhmmss.fff and
can be converted to "units since any-basetime".
The time axis written out to netCDF file follows the netCDF
conventions.

User should refer to EPIC
Systme Library User's Guide for details about data files.
On-line MexEPS Matlab
help is also available.

Another Mex-function provided with this package is **ASCII2MAT**,
which reads a formatted ASCII file into MATLAB as a matrix.

MexEPS programs and examples are available from PMEL's anonymous
ftp: ftp://ftp.epic.noaa.gov/eps/mexeps/.

MEXEPS you must also have EPIC
System library and NetCDF
library built on your system.
- help-m/
--Contains Matlab help script for MexEPS function.
- examples/
--Contains data files and Matlab script programs use MexEPS
function to read and write data files.
- epic.key
--EPIC key code files. This file is required if you are
using MexEPS to read and write EPIC System Data files.

You should set following **environment variables **for
these directories after install all *.mexARCH (where ARCH
is `4' for Sun4 and `sol' for Solaris), *.m files, and epic.key
file:

**MATLABPATH**

directory contains *.mexARCH and *.m (where ARCH is `4'
for Sun4 and `sol' for Solaris); and directory contains
examples.
**EPS_EPICKEY **directory contains epic.key file.
