#include <util/ *.h> -> what's "util"?

[MDR]

Hi

I'm seeking a code for a Standard Value Decomposition (SVD) of matrices and I found his one among others:
http://www.ics.uci.edu/~arvo/code/SVD.C
with the headers included.

But I don't know what is the "util/" instruction that comes with the headers in the include, I've tried to run the program (in Visual c++ 6) and is not working with or without the "util/" instruction, in both cases it doesn't load any header... because I've seen them always being included like
#include < *.h>


Any idea will be wellcome!
Thanx!!

Your reference web site had this:

#include <util/Math.h>
#include <util/Vector.h>
#include <util/Matrix.h>
#include <util/SVD.h>
 

This means the Math.h heade is located along a path from the present working directory(PWD). Something like PWD/util/Math.h.

It really doeesn't matter. You need to a) get the Math.h header file from you web site and copy it to your local machine. If you put it in the same folder as the VC 6.0 project file, you can just include it by:

#include "Math.h"
 

Be aware that Windows file name are not case-sensitive so this Math.h will get confused with the C math.h. Probab;y you need to chnage the name of the Math.h header.

The above applies to all the headers that you include when you use coded from your web site.

Thank you very much for your help!!!

Actually, since it uses <> instead of "", it is not the PWD but the system include directories. It will ignore the PWD when searching for these files.
