I don't believe copy the libraries was important, but obviusly I was using them in my code. Here is with everything else; the segmentation fault disappear, but there is nothing in my console: the...

This is my latests code:




int main(){

double **a;
int i,j;
int nsteps, dim;

O_O

Each time I understand less about this code; when I execute it, appears the "egmentation fault (core dumped)" message. :(

It does't work. My data file, wrt.dat, has the first two lines with two numbers: the first is the number if rows, and the second, the number of colums. My code is like this:




int main(){

Hello again; I revive this topic.

This is the problem: I create a data file, with NSTEPS rows and DIM columns, but I cannot read it using fscanf.

My code is as follows:



for(i = 0; i <...

YEs!!!

I had done this


for( i = 0; i < DIM; i++){
for( j = 0; j < DIM; j++){
for ( k = 1; k <= cont; k++){
p=0;
if( i == s_c1[k][0] && j == s_c1[k][1] ) {

Hi again!


This is my code.


for( i = 0; i < DIM; i++){
for( j = 0; j < DIM; j++){
for ( k = 1; k <= cont; k++){

Yes, I corrected it in my edition of the post. Thanks!

Sorry, no.

I changed my code:




int **prob;
prob=malloc (DIMENSION * DIMENSION*sizeof ( int* ));

&#191;Do you say, instead of use the limits
(j-DIM/2)/25.0, etc., asing each of this limits to a local variable and then ask?



inf_x=(i-DIMENSION/2)/25.0;
sup_x=(i+1-DIMENSION/2)/25.0;...

This is embarrassing, but i have no idea of what is happening.

I'm using numerical integration to solve a ODE, and I asked my program where the final point is. I devided the phase space in little...

I'm trying with this, and at the moment it seems to work fine.



int **prob=(int **)malloc(DIMENSION*DIMENSION*sizeof (int*));

for(i=0;i<DIMENSION*DIMENSION;i++){
...

Ok; thanks a lot. :) (I love C xD)

Perfect! I solved the problem! Actually I got more problems if a don't create the multiple data files, so I did this:



FILE *fp[101]; //number of files I need
char fname[25];

for...

&#191;There is a way to define the array dynamically? &#191;Can I declare it like
int *prob, without giving the size it will have?

ok. I don't see how to write in another way my code. Here is what I'm triyng to do.

I divided and x-y plane in little cell, each of 0.04*0.04. In each cell I started an initial condition of a...

I'm writing a code which implementes the cell-to-cell mapping method.

Finally I know why my compiler is saying me there is a segmentation fault. Apparently it's because I defined a matrix of...

And if my data file are numbers in a "matrix form", i.e., organiced in several rows and columns, when a called fscanf the function will save each data of the file in a compoment of a two dimensional...

This is stupid. I put the last element I was forgotten, and I defined in a correct way i and j.

The thing is that initially I tried to defined the matrix with decimal numbers, like
...

Sorry for post a lot :)

My problem is like this: I have to define an n+n matrix. Obviusly that is not a problem. The question is that in each element of the matrix, I have to define, say, k...

I found the way!!!

I need numbers between 0 and 0.04; next, between 0.04 and 0.08, and so on.

The algorithm should look like this:

r=drand48()/25+i, where i is 0, 0.04, 0.08, and so on.

Hi!

I know you are going to tell me to search in the faq. But my problem is not there.

The thing is this: I diveded the space between -2 and 2, both in x and in y axes, in little cells of...

Ok. The first problem is solved (I save of the data in an unique file.dat).

The second problem is just what dwks say: ¿how can i save the gnuplot's output in different files ITERATIVELY? I need...

I'm not sure I'm understanding you.

You say, put all the text in the same file? That's ok. And that work's fine without additional functions. But I still have the problem with the images files.
...

But rename doesn't work. At last I don't see how.

My problem is this:

1. I solve an numerical integration and I save the data in a file, "file1.dat"
2. I call Gnuplot, and gnuplot uses...
