How do you print to both file.stderr and file.stdout.
What's the command to do that?


(./something.exe > file.stderr) >& file.stdout

??

So here I'm trying to pass multiple stuff through to the function, such as a set of parameters stored in the pointer p, the values of the parameters stored in the pointer paramfile, then some...

I'm trying to call a fuction:


int DetermineEvent(parameters *p, char *paramfile, double X, double u, double dt, int *left, int *right, int *add)

from the main file, what would it look like:...

hehe, I already started to mess around with the code so that I can use it, but thanks for the reminder Salem :)

How many arguments should I pass there? I'm guessing 3: parameter pointer and an...

Indeed I did not write this code, and I'm trying to decipher and take what I need out of it.

I have a code with a number of pre-defined parameters, which are all included in the following header...

int readParameterFile(parameters *p, int argc, const char *const *argv)
{
FILE *fp;
if((fp=fopen(argv[1], "r")) == NULL) {goto ERROR1;}
if (fp)
{
...

haha, just googled it :P thanks for that btw

there are three lists in file that I need to read into the arrays and print out in a different file, for now file.stdout, but it is empty when I run the program, why?

#include <stdio.h>

int lines,i;
double *t, *x, *P;

int main(int argc, const char *const *argv)
{
if ( argc > 1 )
{
FILE *file = fopen(argv[1], "r"); /* Get filename from...

for(trial = 0; trial < N; trial++)
{
nstep = 0;
t = 0.0;
dis = 0;
while(t < to)
{
tau = tao * (1 + g * t);
dt = -log(a) * tau;
u = gsl_ran_flat (r, 0.0,...

ah, figured it out, thanks very much

Hm...thank you all for the responses, but there is one problem with my current code. When I run it, it displays nothing. This is the exact code I used previously and now that code(which was fine...

I just want dis to be any number between 0 and N-1. I just think of it as points on a circle. 0..1..2..3...N-1...N(back to 0)...1...2...3..etc. So there will never be N or negative numbers.

dis is a value that starts at 0 and will change depending on u:

if u is < a/3, then it will decrease 1.
if u is > 2a/3, then it will increase 1.

if the first value u is < a/3 then the dis will...

I need to write a segment of a code where it allows the program to run in a loop basically...so the range of this code is going to be from 0 - (N-1) for example, I want:

if the code happens to...

not currently at my workstation right now, but I'm curious to why nstep would be so huge... nstep has been predetermined and *times has allocated enough memories for maxstep double (which supposedly...

help :)

That's not supposed to be there, instead there should have been a loop that initializes all the b values. =) I just found that out.

The code is working fine, there are some malfunctions in the results, or it could be that I'm misinterpreting it.

I'm running 20 trials.
Each particle has a position after a certain steps.

Thanks, but could you explain to me why my two columns don't sum up to 20 respectively? I run 20 trials, so it should have a registered position for every step of the 20 trials. The table is of...

can you plot 3D graphs with 3 lists of data in gnuplot?

if so, I have data list 1, 2 and 3, what syntax do I use to plot it in 3D?
