bug in math.h
lround, round, and powl and I'm sure others to not show up in math.h.
using namespace std;
int32_t n=lround(440*powl(2, (((double(octave)-3) * 12.0)
+ double(note)) / 12.0));
this is for calculating the frequency of a musical note.
beep.cpp:111: error: 'powl' was not declared in this scope
beep.cpp:111: error: 'lround' was not declared in this scope
I looked at the source code for math.h and what it includes, and it is
supposed to define these two, as does mingw-w64.

I am interested in getting swatch running on about 20 remote servers.
These servers are running OpenServer 5.0.5 or 5.0.6 without a c
compiler. Our local server is running the 5.0.7 Devp system and I'm
able to get swatch compiled and run here so I thought I could just
distribute the related perl files to the remote sites. However, my OS
5.0.7 has perl 5.0.8 and the other servers are running perl 5.0.6. I
noticed while compiling and installing swatch that the local perl
distribution files are modified which is scaring me off that approach.
So, anyone out there got swatch to run on a sy...matlab ==> windows or m.file ==> .exe

Hi, I'm using the following process for my low-pass filter and the
results are very good. I'm getting my coefficiants then convoluting
against my audio samples.
Now when I replace the LP coefficiants with high-pass coefficiants
(cutoff of 1000Hz), there is no filtering at all. The waveforms are
identical. I'm confused as to why there is good filtering with LP
coefficiants and no filtering with HP coefficiants. Any ideas? Thanks!

I have a problem with .mat files. I get some data in mat format and can not open it in windows with matlab 2011b, but succeed by using matlab 2010a on a linux server. Does matlab use different mat format on linux and windows? Is there any function to get in which matlab version and in which OS an .mat file is saved?
Thanks a lot

I want to create a local variable for a boolean button ('Stop'), and use the local variable as a condition of a while loop.
But then the labview will send me an error message saying that "Boolean 'stop': boolean latch action is incompatible with local variables".
So what should I do if I want to control two while loop with one boolean? Many thanks!!

I am learning objective C and wondered if objects called via

Are there any methods in NSArray or NSEnumerator that I could use to
get the index of elements that match the condition? (I realize that I
can just increment a counter int through the loop to get the index
value, but was curious if there was another way as well). Thanks for

I am trying to convert an app from C to C++ on a RedHat Linux 9 system.
This C app uses the "ioctl" function from sys/ioctl.h. Now, I need to
explicitly include ssys/ioctl.h in the C++ app, though gcc finds it just
fine for the C application.
UNFORTUNATELY, the second I include this file, I get a stream of errors
indicating that gcc does not accept the file format of the ioctl.h.
Is there something special I have to do to use ioctl.h in C++?
I would be very grateful for any help.

At the tail end of the module there is a shorter set of "#pragma

with one of them. The disagreeing entry matches the #pragma in
/sys/src/cmd/vl/l.h so I'm not sure which ought to be used (or what
effect the conflict has).

I want to have a random wallpaper on my system (XPPro), whenever I

and saves it to the file name I chose for my wallpaper. I then put
this script in my startup folder to run at every bootup, so the next
time I boot, I'd get a different picture. My wallaper file I chose is
wallpaper_file.bmp, the script then chooses, say, pic1.bmp and then
saves it as wallpaper_file.bmp.
I guess I was naive about how Windows keeps track of wallpaper. This
simple approach fails. The script works fine, but the system is stuck
