RE: RE: RE: 2.9.9+ for Windows

Hi, I found minor differences between Octave 2.9.9+ and Matlab R2006b, all having to do with file access, mostly relating to file permissions (even when these permissions are manually corrected via Internet Explorer ahead of their execution).

 

1.) COPYFILE does not work.  In addition it incorrectly returns a status flag of 1 (successful) even though the copy failed.

Example: [status, msg, msgID] = copyfile(mypath1, mypath2, 'f');

 

Matlab:

status = 1

mypath2 exists

 

Octave, scripted:

Cannot perform a cyclic copy

status = 1

mypath2 does not exist

 

Octave, manually:

Status = 0,

msg = ‘Does mypath1 specify a file name

Or a directory name on the target

(F = file, D = directory)?’

msgID =

 

 

 

2.) RMDIR does not work.  Example:

[status, msg, msgID] = rmdir('myoutsav','s');

 

Matlab:

status = 1

myoutsav deleted

 

Octave, scripted:

status = 0

myoutsav not deleted

echo: Access is denied

 

Octave, manually:

Echo: remove entire contents of myoutsav? (yes or no)

msg = Permission denied

 

 

 

3.)  DIR cannot be used with a wildcard. Example: dir(‘mydirectory\myfile*.bin’)  (Note that GLOB or  READDIR cannot alternatively be used as they only exist in Octave.)

 

Matlab:

Result: myfile1.bin myfile2.bin 

 

Octave:

Result: warning: dir: nonexistent file ‘mdirectory\myfile*.bin’
