Thanks tye!
I saw the link, and tried to read it.
I admit it was quite intimidating at first, but actually quite simple!
Thank you very much!
The script works now!
You've helped me a lot!

For others who might find this thread and need this MAT saving routine from Perl,
below you can see the modified function. Works perfectly now (with binmode activated)!

Thanks,
Koby 

sub mat4_write
{
# Variable name.
my $name = shift;

# Number of rows.
my $m = shift;

# Number of columns.
my $n = shift;

# Matrix elements in column major layout, this is the native
# Matlab storage layout for matrices.
my @a = splice (@_, 0, $m * $n);

# File handle.
my $h = shift;

# use binnary-mode:
binmode($h);

# Type flag.
my $type = $mat4_type;

# No imaginary part.
my $imag = 0;

# Length of variable name including terminating null character.
my $len = length ($name) + 1;

# Encode and print matrix.
print ($h pack ('l5Z*d*', $type, $m, $n, $imag, $len, $name, @a));
}
