Once you have compiled and linked your MAT-file program, you can run the

stand-alone application you have just produced. This program creates a

MAT-file,

matdemo.mat, that can be loaded into MATLAB. To run the

application, depending on your platform, either double-click on its icon or enter

matdemo1 at the system prompt.

matdemo1

Creating MAT-file matdemo.mat ...

Done creating MAT-file

To verify that the MAT-file has been created, at the MATLAB prompt enter

whos -file matdemo.mat

Name Size Bytes Class

Numeric 3x3 72 double array

String 1x33 66 char array

Grand total is 42 elements using 138 bytes

Note For an example of a Windows stand-alone program (not MAT-file

specific), see

engwindemo.c in the <matlab>\extern\examples\eng_mat

directory.

Reading a MAT-File in Fortran

This sample program illustrates how to use the library routines to read in the

MAT-file created by

matdemo1.f and describe its contents.

C matdemo2.f

C This is a simple program that illustrates how to call the

C MATLAB MAT-file functions from a Fortran program. This

C demonstration focuses on reading MAT-files. It reads in

C the MAT-file created by matdemo1.f and describes its

C contents.
