Hi
From: Emmanuel Lanzmann <address@hidden>
# I am faced to two problem (which are very classical):
# 1) I have a file that was written with math Lab, so a "***.mat"
# file.
# I tried to open it using load -mat-binary, but it fails telling
# me :
# error: load: can't read binary file
# error: load: trouble reading binary file `xyzsimple.mat'
# error: evaluating index expression near line 21, column 1
# Is there a way to read this file ?
Sorry, I don't know.
# 2) I need to import some image saved in ppm. I tried the command:
# [M,ppm]=loadimage("....") but it fails.
# How should I proceed to download ppm images ?
You can use Ariel Tankus's (http://www.math.tau.ac.il/þarielt/)
imread() and other functions. I've done some wrapper's around Ariel's
functions so that images be represented as a single struct, if you are
interested, they are at http://anonimo.isr.ist.utl.pt/þetienne/octave.
Some day, they should be on octave's repository at Sourceforge
(http://octave.sourceforge.net/).
Hth,
Etienne
