XLSReadWrite and Octave for Windows

[Ian Journeaux]

I was wondering if the XLSReadWrite package was available for Octave under
windows (32.bit)?

When I try to use XLSWrite I get the following error message 

octave-3.2.4.exe:2> xlswrite('c:\testt.xls',a);
ncols =  256
Creating file c:\testt.xls
Supported interfaces:
warning: No support for Excel .xls I/O
error: oct2xls: unknown Excel .xls interface - NONE.
error: called from:
error:   C:\Octave\3.2.4_gcc-4.4.0\share\octave\packages\io-1.0.11\oct2xls.m
at line 100, column 3
error:
C:\Octave\3.2.4_gcc-4.4.0\share\octave\packages\io-1.0.11\xlswrite.m at line
160, column 6

That seems to indicate that Octave knows something about XLS but not enough
to do anything.

 Hi,

May I please ask how one could find out the audio bit depth that's being
employed whilst Octave is running on one's PC?

Thanks in advance for your kind attention.

Regards,

          Joseph Gatt

I'm also running MacOS X

        octave:1> backend fltk
        octave:2> load octave_binary_data.txt
        octave:3> tic (); contour (tof, hoek, I); toc ()
        Elapsed time is 114.879 seconds.
        octave:4> whos tof hoek I

        Variables in the current scope:

          Attr Name        Size                     Bytes  Class
          ==== ====        ====                     =====  ===== 
               tof         1x1024                    8192  double
               hoek        1x280                     2240  double
               I         280x1024                 2293760  double

However, with a simple example ...

        octave:5> x = linspace (-3, 3, 1024);
        octave:6> y = linspace (-3, 3, 280);
        octave:7> z = peaks (x, y);
        octave:8> tic (); contour (x, y, z); toc ()
        Elapsed time is 0.329376 seconds.

        octave:9> whos x y z
        Variables in the current scope:

          Attr Name        Size                     Bytes  Class
          ==== ====        ====                     =====  ===== 
               x           1x1024                    8192  double
               y           1x280                     2240  double
               z         280x1024                 2293760  double


The slow-down is proportional to the number of patches (3297 vs 16 for the
above) created in by the subfunction add_patch_children() which is in
__contour__.m.

If the creation of the patches (lines 336:366) could be vectorized the slow
down would be substantially reduced.

I'll file a bug report.

Hi Joseph,

``octave:3> record(5);
Please hit ENTER and speak afterwards!

5+0 records in
5+0 records out
40000 bytes (40 kB) copied, 5.12878 s, 7.8 kB/s
cmd = dd if=/dev/dsp of="/tmp/oct-4MT1kT" bs=8000 count=5''

It appears that there were 5 seconds recorded, with 8 kHz sampling. Assuming
that 7.8 kB/s is 7.8 kByte per second, it seems to be 8 Bit depth per
sample. There is a setaudio() function, but I am not quite aware what it
takes.

Best,
Gaston

  Hi Help

I do the following command with unexpected results... any ideas what i 
need to do to make it work?

I'm rather new to mac's and programming but had a look for the 
config.log but it didn't show anything I could understand.

Any help would be much appreciated

OK, I see now that there is a problem with the octave.org DNS
records.  I think I've fixed it but it may take a while for my change
to propagate through the intertubes.

You probably need to install a compiler on your system. For Apple
products, I understand it's available in some installation media that
came with your hardware.

I believe it's also possible to get precompiled binaries, but an Apple
user would know better than I do.
