Re: [Help-gsl] How to return a pointer of gsl_vector

[Ralph Silva]

Hi,

try this.

Regards,
Ralph.

/***********************************/
#include <stdio.h>
#include <gsl/gsl_vector.h>

gsl_vector *one_function();

int main(){
  gsl_vector *tmp;

  tmp = one_function();
  printf("Testing %f\n",gsl_vector_get(tmp,50));

return 0;
}

gsl_vector *one_function (){

  gsl_vector *tmp2=gsl_vector_calloc(100);

  gsl_vector_set(tmp2,50,-999);

  return tmp2;
}
