Bug No- 5466 Advice needed

[shankhs ch]

HI
I reproduced the bug using the program given in the 5466 bug page
http://bugzilla.scilab.org/show_bug.cgi?id=5466 :

A = sprand(400,400,0.01);
B = sprand(100,100,0.1);
unix('rm test_matfile.mat'); // be sure not file like this one exists
savematfile('test_matfile.mat','A','B');
clear
loadmatfile('test_matfile.mat','A','B');
size(A)
size(B)
clear
A = rand(10,10);
savematfile('test_matfile.mat','A');
clear
loadmatfile('test_matfile.mat','A');
size(A) // It should display a size like 400 x 400 instead of 10 x 10

The output is indeed 400. 400. But the logic says that it should be 10. 10.
isn't it?
I think I have identified the problem which is :
"deletion"/"creation of another file with the same name( test_matfile.mat
)" fails once the file is "created"/"if present in the directory as a result
of previous execution" using the *unix('rm test_matfile.mat'); *command.
Moreover the file is getting appended instead of getting created fresh
everytime which is causing the complained behavior.To check this, run the
above program and execute a number of times , check the filesize after every
execution.

I wanted to write this one in the bug page but since this is my first time
and I am new to scilab so I thought its better to ask you guys.
Any thoughts and advices?

Thanks and regards
shankhs
