matOpen (MATLAB Application Program Interface)

Opens a MAT-file

Fortran Syntax

integer*4 function matOpen(filename, mode)
integer*4 mfp
character*(*) filename, mode

Arguments

filename

Name of file to open.

mode

File opening mode.

mfp

Pointer to MAT-file information.

Description

This routine allows you to open MAT-files for reading and writing.

matOpen opens the named file and returns a file handle, or 0 if the open fails. Legal values for mode are:


`r`	Opens file for reading only; determines the current version of the MAT-file by inspecting the files and preserves the current version.
`u`	Opens file for update, both reading and writing, but does not create the file if the file does not exist (equivalent to the `r+` mode of `fopen`); determines the current version of the MAT-file by inspecting the files and preserves the current version.
`w`	Opens file for writing only; deletes previous contents, if any.
`w4`	Creates a MATLAB 4 MAT-file, rather than the default MATLAB 5 MAT-file.

Examples

See matdemo1.f and matdemo2.f in the eng_mat subdirectory of the examples directory for sample programs that illustrate how to use the MATLAB MAT-file routines in a Fortran program.
