If you're refering to www.fftw.org then you'll have to compile the fftw-library. Just follow the instructions in the manual .

I think, manmohan means the following:

The modulo operator % does not return a floating point value as you imply by writing 0.0.
From the ANSI C99 Standard:



number%2==0

Shiro, thank you very much for explaining your "OOP in C"-technique. That's exactly what I've been looking for.
I've been working on a new version of my scientific project for months. I am still in...

You're right. Now it's quite obvious to me why the code is valid indeed. And thank you for the link. :)

typedef struct info {
int x;
char name[10];
}info;

Hmmm ... I think this is invalid code. "info" two times ... that doesn't work.
This should be correct:


typedef struct {

The ANSI C99 standard already provides a boolean data type.

#include <stdbool.h>

bool/true/false

Another reason for me to migrate to Linux completely! If I remember correctly, Linux Kernel >=2.4 supports SSE ... I will check my Debian installation.

Thank you very much for your help, Codeplug!...

Does this mean I have to run the test program as an administrator?
W2k forces admin rights in order to use SSE instructions? That sounds crazy to me ....:confused:

I've just tried "run as" admin,...

This is my first try with GCC inline assembly. I followed an example from this paper (page 3) and wrote a small test program:


#include <stdio.h>

int main()
{
int i;
float a[4] = {2.0},...

I've never used complex numbers before, but wouldn't it be better to use the complex arithmetic built into the ANSI C99 standard?
<complex.h>

You must either allocate memory for your team names or just initialize the array of structures as follows:


teamType *teams = { {"Arsenal FC", 5, 0, 0},
{"Newcastle Utd", 5, 0, 0},
/* and...

The tutorial is for C++, but maybe it helps a little bit.

I love google! ;)

Here is a wonderful explanation including source code (I think it's Pascal) and animated GIFs. :)

Please, try searching the forum next time first. These standard questions have been asked many times before.

As already noted by XSquared use:


int main()
{
...
return 0;
}

int amount;

Aha! That makes sense to me.

That's good news. I thought about it yesterday, but didn't find the time to ask.
Thank you very much for your help, Prelude. :)

That explains the segmentation fault. So, a function pointer is a different beast?
Is the true implemenation of function pointers quite different from normal pointers?

@return NULL and function...

Dave, that's a neat implementation. I think it's easier to understand than my version.
Thanks alot! I will implement your solution.

@double comp:
Hmmm ... I didn't spend much time thinking about...

typedef makes life easier ;)

I am sure that nothing is wrong with my typedef of function pointers.

/* function pointers to comparison functions */
typedef int (*DoubleCompFunc)(double, double);
typedef int (*IntCompFunc)(int, int);

/* comparison functions */
static int cmp_lt(const double a,...

Oh, I thought the doctor prescribed you ibuprofen. I guess, it's time for a Doc. I hope it will not get worse!

I still wonder if I am actually able to type my thesis ... :(

@ibuprofen and swelling:
Okay, that's different! I don't have any visible symptoms. You may very well need the anti-inflamatory effect of ibuprofen! :eek:

@lurking on...

Welcome to the club ... :(

I would be careful with medicine. It may reduce the pain, but the root of all evil is still there! So, you may well increase the damage done to your forearm/hand,...
